Title: 70 Challenger Conv. Resto Mod-6.1 Hemi
Post by: soundcontrol on December 07, 2014 - 02:23:00 PM

Just started taking my car apart so itīs time to start this thread. I donít have an exact plan for it right now, but my immediate plan is to get the suspension and brakes on the car and try it out to see if this is what I want, or if I need to do further modifications. I listed some parts I bought for the car below. The only thing I did so far is mounted the subframe connectors, and it was a big improvement. I hope I will be happy with the suspesion, steering and brakes.


 I will start with taking the engine/tranny/K-frame package out from under the car, first time for me, I removed engines from my 5 earlier e-bodys numrous times, always from the top, so this is gonna be fun.


When finished, I think it will be a black R/T clone, with a Hemi in it, old or new Hemi, I donít know. For now, upcoming couple of years I will use the 340/727, maybe with a supercharger, or an SFI system just to spice it up a bit. The plum crazy paint is good, so Iím not gonna touch that right now. (and my wife loves itÖ)
I donít think it has a any bad rust, except for the trunk floor that has a few bad spots. I would really like to have it in perfect shape, and a rotisserie restoration is on my wishlist, but right now I do not have the space, time or money for that. Itís an AC car with no AC parts left, a broken fan motor and a leaking heater core,  so I bought a Vinage air system for it.


I guess itís a resto mod, since Iím changing a lot of parts to non OEM. I really like the OEM restoís that people here do though, I hope I can get that quality in my work. Iím saving all original parts for later.


Just checked my VIN numbers on the cowl and behind the radiator, all OK.
Some pictures will follow.

Can't go wrong with better brakes and suspension.  Looks like the car is already in great shape too.  Beside the gauges, are you going to make any mods to the interior?

I had thoughts of replacing the seats for more modern ones, but I don't know, I really like the look of the stock interior, maybe I just get legendary leather seats and try to add some foam for a firmer seat with more support, if it works. A 6 way electric seat would be nice if I can find a bottom part that will fit. hard with the 2 level floor pan on the e-bodys. The rest of the interior will be stock but restored, I also need a nice stereosystem with subs in the trunk.Gonna try to soundproof the car as much as possible, get all the rattles out of doors etc.

Not a lot of progress lately. Starting to disassemble. Got my K-frame stand done. I cant get the T-bars out, I loosen the LCAs and moved them back a bit, I can see the T-bar move in the LCA socket, so the LCA moves back but the T-bar seems to be stuck in the crossmember, I tried to use a pipewrench on the T-bar and hit it backwards with a hammer but all I do is scratch it. Can I move the LCA even further so it pushes the T-bar out of the rear socket? or is there any other trick to this? (I did take out the snapring in the crossmember socket).

Undo the upper control arms from the spindle. Support the K frame with a floor jack. Remove the four K frame bolts and then pound the K Frame forward off of the torsion bars.
Nevermind..
If you're replacing the torsion bars, then just cut the darn things...

I guess I have to remove the strut rods also, so the LCA goes further back, didnt do that yet, I got the LCA about 1/2-3/4" back but that was not enough to move the T-bar. Dont wanna cut them, want to keep all my stock parts. I'll try again soon.

Yes remove the strut rods , they should come out with some effort

Success today. Got the T-bars out. Started out trying to make a clamp that I could hit with a hammer, no go... need a much heavier clamp than my lame one, see pict. 1. Next I removed the strut rod and then I could hit the LCA even further back, and that did it. On the drivers side it was easier, did not even have to remove the strut rod there.
UCAs, 3 of the adjustment bolt came out fine, the forth was stuck, seem to have rusted in the bushing so I had to use a lot of hammering and prying to get it out, bushing was trash. Only thing left now before I lift the car is to loosen the steering column. Floor jack fitted nice under my K-frame stand. Anyone knows what size the K-frame bolts are? (Need to get a new socket, my largest one is 1").

My rear transmission mount, is the shifter support bracket originally mounted to the transmission mont like this? This is my first small block Mopar and I dont remember my big block cars having the bracket there. Think it was monuted on the transmission. And what is the extra bracket facing forward on the tranny mount?
Title: Re: 70 Challenger Conv. Resto Mod
Post by: johns cuda shop on February 01, 2015 - 05:45:29 PM
It is mounted on the tailshaft .Some transmission tailshafts don't have the bosses that is why someone welded it to the crossmember.

Aha, the car probably had a 904 originally (G-code) so someone put this 727 in with the 340.

If you use jackstands in front of the rear wheels in just the right spot you can lift the front of the car by hand.

Post by: soundcontrol on February 09, 2015 - 07:42:06 AM
Success, that was a cool way of getting the engine out! Not as easy as it seemed on other peoples pictures, but my main problems were to dissasemble the parts thats not been touched for 44 years, K-frame bolts took forever to get out, very rusty, thought I would bend the frame at one point. Next time I will make a lift tool that hooks up to the bumber mount holes in the frame, (US Car Tool sells one) since the engine hoist wheels was kinda in the way and it was a bit tricky to roll it out.


Brad, yes that would work, I noticed that the car is not that heavy in the front, a bodybuilder could probably lift it as is...
but I was by myself today so it was not an option.

A little bit of progeress today, I got the engine up in my stand. Can anyone ID my 340? I assume is a -72, according to the casting numbers I can find, is there any other number I should check? Serial number is unreadable during to paint, I will remove the paint later and look at it.
I read somewhere that you can tell if the crank is cast or forged by looking at the balancer, I dont know what it should look like, my converter did not have any balancing weights on it though. Removed the bracket for the power steering pump, those bolts seem to go right in the coolant area, no wonder it leaks water, no sealer at all on the bolts there.
Title: Re: 70 Challenger Conv. Resto Mod
Post by: soundcontrol on March 01, 2015 - 04:08:02 PM
When I bought the car I had no idea what shape the engine was in, taking the heads off now I see I have +030 TRW L2316 forged pistons, and the cylinders seems fine with no edges. Camshaft and lifters seems fine. Heads are probably from a 360, casing number says 340 or 360 but there is a big 360 cast on there also. Gonna see if I can figure out what camshaft I have tomorrow, and take the oilpan off and check the crank and bearings.


Now, taking off the left head I get a bunch of coolant all over the place, seems like the head gasket (Feel-Pro I think) blocks a coolant channel so it stays in there, Is that correct? (or did someone use a wrong type of gasket). Found lots of problems taking it apart, a cracked sparkplug, double header gaskets (been leaking) 2 headerbolts broken so I have to drill them out later, big bolt holding the balancer on the crank loose (so the balancer was loose also) , intake bolts missing etc.


The number, on the lower right edge by the engine mount, is that a part of a VIN for the car it was in originally?

Post by: rUNCHARGER on March 01, 2015 - 06:16:53 PM
Engine is out of a 73 car, those are forged 10-1 (nominal) pistons. I couldn't quite see the balancer to see if it was for forged or cast crank. 587's are 360 small valve heads I believe. They will wake up with 2.02 intakes and a light cleanup of the ports. I'm not a smallblock guy but hopefully this helps a bit.

Post by: rUNCHARGER on March 01, 2015 - 06:19:55 PM
Yes you are correct that those are the last #'s of the VIN on the oil pan rail. The first 3 indicates the year of the car, B is Hammtramck.

Blasted some small parts today, including the LCA's, now, does the adjustment arm in the center of the LCA (that the torision bar adjustment screw is moving) come loose when I get the LCA rubber bushings and pin out? Reason I ask is that when I move the adjuster, I can feel that a lot of sand came in between there after blasting. I need to clean it out.
Title: Re: 70 Challenger Conv. Resto Mod
Post by: 1 Wild R/T on March 08, 2015 - 02:35:18 PM
At won't come loose, it was put in place before the arm was welded together... Rotate the torsion bar anchor in the arm a little & most of the sand will fall out pretty quickly... Since the anchor doesn't move in the arm when the car is assembled it's not an issue anyway...

I read somewhere that you can tell if the crank is cast or forged by looking at the balancer, I dont know what it should look like, my converter did not have any balancing weights on it though.


Here is my 340 Cask crank balancer, clearly marked for a 340.  The pic shows a forged steel crank. A cast crank has a thin line from the casting molds.
picture of a forged steel crank parting line:

340 cast crank balancer:

If your engine was rebuilt and balanced, the builder could have balanced everything with a neutral balanced balancer and you still could have a cast crank.
The same for the balancer or flywheel. the 340 cast crank user very little offset balance in the rear. Since you didn't have weights on the converter, some weight could have been taken from the opposite side or the builder could have added or removed weight to the crank. Since you have it out, have it all rebalanced to be sure.  A vibration with drive you crazy.

Thanks Rob! My crank is forged, thats the good news, the bad news is that it has some scratches on some of the main sufaces, and its already at 030 over on both mains and piston rod taps. The engine is in a machineshop now, I'll get a verdict next week to seee if they can polish the scratches off or not.

K-frame blasted and epoxy primed. Now I am going to reinforce it and weld up the seams. I know I should have done that right away before primer, but time wasn't on my side and I didn't wanna let it sit unprotected for weeks, have to clean out the areas to weld first. I wonder if I should go over the factory welds also...seems like they had a bad day at the Hamtrack plant welding dept. that day my K-frame was made.

Progress has been slow. Summer is approaching fast and my work is taking up all my time, I hope I'll get it done soon. Engine is in pieces and so is the suspension still. Got a few hours this weekend to weld some, my K-frame seems to be put together very sloppy, edges and holes don't align at all, I'm just gonna weld the edges up and cut the the excess material so it looks nicer. Steering and engine  mounts are welded on just on side, should I weld them on both sides toward the K-frame? I need a MIG to get in there, can't reach with my TIG, and even if I get in to certain spots, I can't see what I'm doing. This seems to be my main problem with the TIG, having a good view over the process.

I sure hope it did not warp! I welded an inch at the time, then cooled down that area with a cold wet rag, and then continued welding at the other end of the K-frame. And I did this over a period of 6 days, not all at once. I did all the edges before I reinfoced the steering box mounts and rest.
Btw, all that soot is from the paint catching fire.
But now I got worried.... :scared:




..a week later, checked the K-frame, its fine! Fits perfect in the car.  :bigsmile:

LCA's are almost done! Just gonna mount the Firmfeel swaybar brackets, they bolt in but I think I'm gonna weld it in addition to the bolt.
Now I think I did a mistake by taking out the outer metal sleeves from the old LCA rubber bushings, my new poly bushings with greasable pins are way to small now. Looks like they fit in the old sleeve, but too small for the hole in the LCA's now. Can I use standard rubber bushing with the greasable pins? (no need for grease though...) I think I have a pair of standard bushings somewhere, or should I remove the outer shell from those and use it with the polys?

Use the standard rubber bushing.... If the grazeable pins are machined larger for the poly bushing send them back.... Use the OE pins... I've said this many times & it's been said by guys with a lot of road race experience too... Those poly bushing allow the inboard end of the control arm to move forward & back ... With a GM there's so much rubber the control arm floats so polls are needed... On a Mopar there isn't much rubber and because of the design polys don't work well... Put rubber back... :2cents:

Gonna paint the LCA's, I like the cosmoline look on OE restorations even though mine is not. I bought some gold metal paint, but it's too light, gonna try to make it darker, what could I add to the gold to get the look? Brown, red, black maybe... From all pictures I see Cosmoline looks like more like bronze, or a darker gold to me... I know there is paint to buy that simulates Cosmoline, or Krylon battery protector, but not here in Sweden and I don't wanna order from the US.

You can mix brown and yellow to get gold. If you want, you can add a little red at the end.   :bigsmile:

Added:  Forget the red.  In your case it would only be a few drops and I'm being excessive.  Start by mixing the brown and yellow about 50x50.  To make it brighter, add yellow.  To make it darker, add brown.  Make sure you measure the paint you mix and keep up with the percentage in case you need to reproduce it.   :2thumbs:


Cool, gonna try that, I already bought gold, was a bit light, maybe I can add brown to that..
Thanks Jim!

I learned a lesson, don't mix paint on the kitchen table under a lightbulb! I mixed the first coat way to dark, looked great under the lightbulb, but really dark brown outside, so I added a lot more gold to the second coat and mixed the paint in daylight.


Cosmoline....nah, but hey, it's a restomod, I can paint them pink if I want : ). OE guys won't like it, I do though.
I used gold, red and green, I figured since red and green makes brown, I have a bit more control. It's the best I can do right now, next car I'll get closer... Picture is a bit dark, it's lighter IRL.


Got POR 15 Metal Mask for my spindles, steering arms and steering box. I think I can brush that on.

Finally, a day off from work so I could paint the k-frame, spindles etc. Used a 2k primer on the k-frame and a 2k black in 2 coats, looks nice except in a couple of spots where I can see some grinding marks that I thought would be covered up by the primer, bugs me...
Used a long angeled brush to paint inside it, think I covered all surface in there. The spindles are painted in POR 15 Metal mask, looks great on stuff thats been blasted and has a rough surface, gonna use it for the steering box and linkage also. I also painted my new strutrods with that, but those are more smooth and the metal mask paint dont look as good on smooth stuff I notice, so I'm gonna sand those down and paint them black instead.

How do I clean my 727 tranny best? I'm only gonna change the oil and filter in it, before I put it back with the engine, but its dirty and old looking. I bought some alu wheel cleaner, gonna try that, after a good hi pressure wash. But any tips are appreciated.

Post by: ShelbyDogg on July 17, 2015 - 06:20:38 PM
Get  some good oven cleaner with lye in it, scrub it with a wire brush, pressure wash it then spray it with a good silver paint. If it is out, pop off the front pump and change the big o-ring, paper gasket, and front seal. Easy to do now, a b!tch to do later.

Thanks, got the oven cleaner, did a little test, alu wheel cleaner, oven cleaner, brake cleaner, and a Castrol cleaner. They were pretty similar, but the brake cleaner appear to be a little better than the rest.


Now, does anyone know what the extra bracket on my tranny support mount is for? Pointing forward, nothing attached to it. I'm gonna cut it off so it looks cleaner.

I've seen those before, back in the 80's I was told by many vendors who were selling them that they were OE Mopar & correct for our cars.... What I believe they really are is OE Mopar from truck applications the bracket was used as an attachment for a exhaust hanger...

Personally with as many cheap junk tranny mounts as I've seen fail I usually use a urethane mount, it's a good application, never fails, dampens enough vibration, much better than the junk mounts being sold by most suppliers...

Yes that mount is what I call a generic version. Less part numbers in inventory for more vehicles.  Challenger does not need it. I cut it off mine also.

Yeah, I know, I kinda lost wind for while... heavy duty work for 8 weeks straight, 90 Hr weeks, nights/weekends. After I finished my work project, mid August, I became a zombie, landed on the couch with the remote and a beer, couldn't get up. Kinda mentally exhausted. My goal was to drive it this summer, that won't happen now, summer is over here. So now I'm thinking about selling the fresh 340 and get a Hemi III for next summer.... Just a bit scared that the swap will take longer than I plan and it will still be in the garage next summer. Thanks for poking me though! Now I feel the urge to continue with the car.

Yes, works fine with stock K-members, just use a midsump oilpan, and get a oilfilter adapter or relocation kit. I just wonder if those stock exhaust manifolds will fit...or if I have to get headers.

Well, 10k is my swap, I live on the other side of the planet so I pay expensive shipping costs, custom fees and sales tax. WIth a free 5.7, you could probaby get away with 2k of extras.

Finally I got some stuff done, got the front and fenders off to weld in the USCartool braces, bad thing is, I was not careful and chipped the paint on the driver side door edge removing one fender.  :swear:


My car is put together with all kinds of screws, and different sizas also, metric, woodscrews, you name it... and the fenders had some type of glue under the screws also, suspect construction glue, looked and smelled like it, and it was hard to get the fenders off. Check out the pict of the fender bolts, dont look correct to me. And the upper corner bracket thats bolted to the cowl was not bolted at all, loose, same with a few bolts in the front that attaches to the radiator support. No wonder my car is a rattlecan!
Is there any type of sealer that suppose to go where the fenderbolts in the engine compartment are? At least not glue I guess....See pict.

I will have to get a new bolt kit for the whole car I think, interior is a huge collection of different screws, I found drywall screws holding door panels!


...and I checked my numbers on the radiator and cowl, weird, I got B0 and my correct serial No, it should say 0B (0 for 1970 and B for Hamtrack) but the reversed it, both on the cowl and radiator support.

Well, 2016 didn't start out great, I spent hrs cutting and welding the rear wheels of my cart for the body together, used my old leaf spring hangers for the rear body mounts. Efter painting them and trying to get them on the car I find out that I welded them on upside down! The 4 bolt pattern is not symmetrical, the 2 lower bolts are wider apart, so they do not fit this way. :banghead: :banghead: :banghead:



And I even drilled some extra holes for more weld area!

And I'm now out of gas in the TIG, shop opens monday....
Oh well, do it again, and do it right.

Fixed the problem today, put a few tacks and testfitted first, like ShelbyDogg suggested. Will do that with everything from now, its very easy to screw up welding parts together. I could actually weld for about 15 minutes with the gas indicator on 0, so I managed to weld them up.
Now, my wheels are no good, rubber is too soft, even though they are classified for the weight, so I need to change wheels, very hard to roll the car. It's gonna go on my rotisserie soon, I will not use this cart right away, the rotissery wheels are good, hard rubber, rolls easy.

Heat volume is what worked best.

Yup that's the ticket.  But watch the heat.

Actually it is pretty easy, you are not trying to melt the UC, you just want to warm it up, it will solidify harden slightly and can be easily scrapped off. You can visually see it change, once you get a feel for it you will be good.

I took the oportunity to finish up my cart that I'm gonna use after the rotisserie work is done today, while I have easy access. Here is how I did it, I put the front wheels as much forward as I could, and used an excisting hole in the frame to get a bolt thru. The cross pipes are removable for easy storage and so I can get the tranny in there on a jack to testfit it later. This time I spotwelded and testfitted everything before welding!  :)
Think I'm gonna paint it also, so it dosent rust. First I got cheaper wheels with more rubber, car would not even roll.... had to return them. Theese are good (and expensive).

Removed the quarter windows, that was way easier than I expected. Looks pretty good inside there, except for a bad patch in the lower corner that someone did from the outside, and did not weld in right, have to redo those (same on the other side).


Whats the best way to restore the window mechanism? Glass blast? How do I treat them to look good and not rust?

What I did was sprayed Brake Kleen on the greasy parts them soaked them in Evaporust.
Before re asembly, re greased moving parts with Lithium grease.

Damn, the thick undercoating comes of easy, but under the front fenders there is a thinner undercoating applied, this one is way more sticky, and not easy to remove. Heat makes it softer, but also stickier, paint thinner seems to dissolve it somewhat but it just spreads it out. Inside of my fenders are also treated with this. I guess its a good rust protector though.

This is the only rusthole I found after stripping all the undercoating off. Its the wheelhouse towards the trunk. I will change the trunk extensions, (no rust, but they have been cut off at the bottom and dont go all the way to the quarter panel bottom edge). Now this hole is in the middle of the split of the wheelhouse, and where the trunk floor meets the trunk extension, how do I repair this best (and I'm a newbie with bodywork). Do I make 2 patches for the wheelhouse? One for each half? The trunk floor is fine, and the extension will be new.

Some progress. I got my 340 sold and delivered, and I got the Hemi up in the engine stand to change the oilpan etc. Now, I have never turned an engine around in the stand with the heads on, and I have not seen it done either, I saw that when they changed the oilpan on a car show on TV that they did not turn it either. Is there a balance problem, will it tip over? Would be nice to turn it for the oilpan change.

Still haven't turned the Hemi over, I will do it this week. I was gonna repair the bad patches in my trunk floor the past week, I made a new one, came out pretty good, (I know there is supposed to be another pressed square part in it, but thats out of my league right now), but I also noticed that the area around it from the trunk side was pitted, easy to burn thru welding, there was some heavy layers of paint inside the trunkfloor and I grinded off most with a wirewheel, found 5 more spots in different places on the trunk floor I have to repair, now I think the best solution is to get a new trunk floor.

Looks like you're doing it right. It took me 14 years to complete my #s '70 Challenger R/T vert. I purchased in '93 and got it finally finished for the'08 Nationals.
It's time and money, for me working side jobs while trying balancing work with family. I sold it in '12 when economy took it's toll and I cashed in the bank account
for more important needs. I got back in the market last year with a "71 Charger R/T this time. my retirement present. Kept the 440 with a slight mod build, then
added a 5 Spd. tremec, 4 wh discs and 17" Americans. My grandson calls it Grandpas Noisy Car, but it's a blast.
My youngest son just bought a clean '74 Cuda that I found down here in Florida. It's a good start for rebuild, his plans are to install a Gen 3 5.7, tremec 5 spd.,
Hotchkis suspension. He has me to do the work but funds will take him awhile and Dad won't help on that end. If he wants I'll start puling it apart later this winter,
the original Powder Blue has got to go.
We'll follow your thread and wish you good luck with your build. During my Chally project I continued to keep interest by going to shows knowing one day I'd get it done.

Finally! Some time to myself so I can work some on my car. I started to put the bottom part of the Hemi together, got the wrong oil pickup from Bouchillion so I cut it and reclocked it, TIG welded it, that was faster then them shipping a new one to Sweden. Got the Milodon oilpan mounted. Now I'm gonna clean the engine and repaint the hemi orange on the block. Also painted 2K epoxy inside the US Cartool fender braces (with a brush) before I'm gonna weld them in, gonna be hard to get to when done, going to spray a black topcoat also, and paint the stock fender brace, and area under there black.

Started with the inner fender braces. There's a Whole Lotta Grinding Going On here...
Had to add some material also. I'm also painting the area under the pieces I'm welding, gonna do the same inside the big fender brace.
After welding I'm gonna apply Eastwood internal frame coating to cover the welds.


Unfortunately I found some more rust that even the sandblasting did not reveal. Someone had put a big chunk of weld on top of it, when I tried to grind it down to make it look nice I found rust, and I could poke a hole in it. Its in the corner area of the cowl, glad I did that, that will eventaully had rusted through and caused a leak in the inner firewall. So now I gotta fix that before I can continue with the fender braces. Looks lika a tricky part to make a patch for, I also gotta repair the top overlapping part of the upper cowl. Oh well, I'm up for the challenge.

Fixing the rust, looks simple, but it was really hard to make that corner patch, to get the top curve right and fitting OK, thats my second attempt, first one failed. Have to weld some from the inside of the car, since the upper cut is inside the cowl area. The overlapping piece, corner of the upper cowl is gonna be even harder, has a curved ridge in it.

Finally got the right side almost done with the inner fender brace, biggest time consuming thing was the little rust that had to be fixed before, and making a sliding nut for the hood hinge. I just tack welded the underside for now, I will weld that up when the car gets back in the rotisserie, since I suck at welding from under. Painted the inside of the brace and all the areas I cant get to later with 2K epoxy primer and a black top coat. Now on to the driver side!

Looks like a great job on those bracing welds. The USCar Tool inner units look like something that came off a Tiger Tank, definitely heavy duty, especially compared to the factory braces.

Yes, they seem to tie the shocktower to the firewall really good, also gonna weld up the shocktowers more. And put in the lower radiator supportbrace. Thinking of making a support for the upper radiator brace also.
Found rust in the driver side corner also, starting to fix that, made the first patch.

Almost done with the drivers side now, just gotta weld it up, first I gotta fix an exhaust system for the garage because the ventilation in there is bad and its small, when I weld for long the air gets extremely bad in there. Got the parts, (long vent pipe in the car, a hose and a big powerful fan), gonna build it tomorrow.Not super happy with the fitment of the inner fender braces, can the cars really be so different that I have to ad 1/2" of material in places and grind off 1/2" in other places...?
