Title: 1970 Cuda EK2 Build
Post by: Cazbah362 on January 01, 2017 - 02:35:10 pm
Hello all, I wanted to share my build on my 1970 Barracuda which I bought in late 2014.  I bought the car from a local Mopar guy - I wanted I was looking something non-numbers matching, but with a little spunk for a nice all around build (pro-touring, drag, daily and a little spirited if needed).  This car popped up, and fit my needs.  1970 Ek2, no frills options, with 318 and 4 speed, all non-numbers. 

To date, car is painted with a 470, TKO600 5 speed, 8 3/4 with 4:10’s.  I just finished the rear end with 489 with 410’s, EPSO springs, AR hangers, powder coating and Hotchkis sway bar.  This matches the front which has reenforced lowers, Willwoods, factory sway, and all powder coated. 

My ultimate goal is to make this all an “digital” car.  Right now I have a Dakota Digital dash, Megasquirt Pro, and a few other gadgets which are or will be installed to leverage their potential.  I have a 451 which i am building (whole separate thread) with fuel injection all the way down to the coil near plug setup.  Right now the carborated 470 will work just fine, I will just use things like TTI’s with 02’s sensors as tuning tools.

Hope this makes up for allowing me to “lurk” on the site for the last year.  Here is a short punch list - with a video below

Punch list:

Interior
1.  Install the side glass
2.  Wrap rear seat

Electrical
1.  DD Install
2.  Dome light
3.  Brake pedal/lights

Body Upgrades
1.  Install roll-bar
2.  install sub-frame connectors
3. Harness -  Belts

To Drive
1.  Front end alignment

Exterior
1.  All seals

Rear-End
1.  Shocks

Glass Install
Seals - all around

Made a little progress over the last week.  Most of my energy has been focused on getting the rear-end pulled, rebuilt and back in.  Pretty much only thing which is original now is the banjo and axles.  The 741 was swapped for a 489 with 4:10's, spool, crush sleeve eliminator, and a 1350 yoke.  For brakes I went with Dr. Diff's smaller disc kit, awaiting the e-brake cables time of this post.  Leaf springs I purchased through ESPO, replaced all the shackles and hangers.  Front hanger supports I beefed up with AR Engineering's heavy duty with backing plates.  The axles received new green bearings and disc studs, nothing to great, just nice to have.   Everything I could have powder coated satin black was done, really turned out nice.  The nice upgrade I did was add the Hotchkis sway bar.  Since everything was out, it was much easier to weld in the required brackets and set it all up.  This weekend I ordered Calverts 9 way adjustable shocks.  These, along with the E-brake cables should be here next weekend.  This will allow me to fix novice double-flare brake lines, weld in tangs for the disc conversion and bleed the brakes. 

While I wait on parts, I installed Rob Yules head light relay kit.  Kit went in pretty easy, no issues but it make me realize my front marker light/drive light wiring is frail, broken and needing to be replaced.  This will another project, and probably after I get it road worthy before spring.  However, it did lead me into doing a partial amp meter bypass and head me into starting my Dakota Digital (DD) install.

Since I had the dash out, I started running all the sensors and related wiring for the DD install.  Right now I gave the TKO's VSS, oil, fuel, and temp sensors wires run to the general location for the control box.  Finding a nice easy access place for the box is my concern, this is a "general" location for the time being. Tomorrow brings another day.  What I need to do is pay for a Rallye Gauge bezel, which I already have with a complete Rallye Gauge system on hold from a friend.  Seems there is more money going out then coming in, nothing a brass pole won't fix for my weekend job.....

Looking good!!!!

I have a question.  I noticed the "carbon fiber" finish on your hood and fender tops - a look I am really interested in having on my car.  How did you accomplish that?  Is it carbon fiber or a decal?

Thanks

Hey Mike,
That is 3M vehicle graphics material.  I wanted to follow the AAR type of vehicle, but in my own personal way, so I made a deal with a buddy of mine who does wrapping and graphics for a profession.  One thing he really expressed was the type of "carbon fiber" material to purchase.  The older 3M and the off brands blemish when touched, lightly damaged or have difficult areas to wrap into/out of.  Based on this, he recommended the type we ended up using.  It went on really nice, no issues or weird stretch areas.  It was about $300 for the bolt, seamless cutting tape, and glue.

Nice build!  I have the same rear sway bar....do you have any pics where you attatched it to the frame....or measurements how far down you mounted it?  thanks in advance.....
Title: Re: 1970 Cuda EK2 Build
Post by: Topcat on January 20, 2017 - 11:52:51 pm
One thing I learned about the rear sway bar is that you have to go the Hotcthkiss rear sway bar set up if you go over sized dual exhaust over pipes.

The factory system has interference challenges if the over axle pipe is a 2.5"

MPL I have failed you, sorry just got focused on other things and spaced the photos. 

So got going on things today and have the installed the e-brakes, bled the brakes and worked on the dash install - oh and shoveled a lot of snow.  I have finished wiring in all the senders for the DD dash and bolted it in.  Did a quick test fire with it and got all the gauges excluding the speedometer working, speedo needs to be out driving to configure.  Here is a quick photo, very impressed with the DD, easy setup. 

Also, yesterday installed the Calverts shocks and set them in 5.  Now we need the snow to go away so we can drive, check and finish things.  And I need to stop procrastinating on seals and the door glass (no fun).

no worries!  I had a factory rear sway bar on mine...I unbolted it from the frame and stuck the hotchkis bar on...Im not sure how close to the factory holes it goes or if I can just use those holes :dunno:..........Ill weld it to the frame when I get it bolted where it is suppose to go....I heard the horror stories about them getting ripped out of the frame!  Thanks

Well worked on things this weekend, still procrastinating on the door glass.  But got the door seals installed, rear end buttoned up and the dash finalized.  My friend came through with the dash, nothing perfect but it was nice enough to install, but not perfect enough I needed to worry about drilling the setting's switches into them  - Can you see them????

EMCD - Yes worth the money!!! and easy to install!  Everything was very nice so far, only thing I have not messed with is the speedometer setup, will need to drive to setup.  The fuel gauge is fantastic - I have a Tanksinc setup and this system picked it right up.  Also other cool feature like 1/4 mile time, 0-60 and others, but again have to drive to use.

CudaKiller - thank you

mpdlawdog - I understand, I am at the point I want to drive mine so - priorities. 

USRaptor and YellowThumper - Yea I am happy to have low options, which provide the build with OTHER options, as for a numbers matching - that attention to detail is a bit much for me, I love these cars, but also love to drive them.  I would get worried with a full numbers matching - but they are beautiful when someone can do them that way. 

Thank you all

Post by: Cazbah362 on April 01, 2017 - 11:48:25 am
So, have not posted much lately, seems there has been a lot going on.  Here is the progress:  First, I have the car out driving, so that is a big deal to me.  With driving, you start working the bugs out.  I had a pretty substantial oil leak which was driving me crazy.  Started by changing the pan gasket from a traditional dual cork and the crappy 440Source windage tray to a modern all in one system.  This worked for most of the leaks, but still had one at the front of the engine.  Only things I could figure is the factory cover was flexing too much with the roller cam or the fuel block off was leaking. 

To fix these, pulled the fuel block off which looked like it may have caught and flexed on the pump rod hex nut?  Tightened the hex nut, flattened the plate and installed a new gasket.  For the timing cover, I bought a AR Engineering cover (expensive) and installed it.  After a quick driver in the neighborhood, seems the Valdez is fixed.   

As for updates and upgrades, what lead to me finding the leak was taking the car to a welder to install the torque boxes, frame connector, roll bar and well up the TTI exhaust.  The guy did a bang up job and definitely welds WAY better than I do.  I bought and installed the TTi with their bands.  This worked well, but had a bit of leaks for the wideband.    As for the USCarTool torque boxes and frame supports,  well the welder said not the best of pieces, but they worked.  Car seems to be a lot more stiff.  Also installed 5 point harnesses from Summit.  Yes, a bit of overkill, but wife wouldn't ride with with me with lap belts.

Next on the agenda is some electrical gremlins.  I think I will be doing a LED taillight upgrade during this time. Also, bought a 2012 5.7 from a manual Challenger.  This will be the winter project.  Right now scrounging up all the items to drop this in.  At this time have the engine, Hemi EFI Gold Box, LS throttle body adapter and flywheel and clutch.  A this time, I just want to drop the engine in and get it driving.  Down the road I will decide how much HP etc is needed for my driving pleasure.  Between now and winter, I will be doing small items, like changing the Areomotive dual pressure regulator and possibly installing an SRT radiator and fan system.     

Well that is it, almost 9am here, wife says I can start the car only after then - pesky neighbors

Off to burn some 100 octane - found at one of the local pumps......

Car has been fun lately, so thought I would change small things.  This weekend I found a Fitech 600 on CL, brand new so i purchased it.  Spent the day installing it, really only took a few hours.  Luck would have it, I had the TanksInc pump and an AN8 system installed, so install went fast.  After basic install, fired right up, albeit a little rough and lot rich.  After a few minutes, balanced it out and ran fair.  Since I locked it out and had the system managing the timing, I set it and idled like a champ.  Now we are in the learning phase.  Here is a video:

Only question I have now is what is a good AF Ratio for a 470?

Title: Re: 1970 Cuda EK2 Build
Post by: Cazbah362 on May 22, 2017 - 01:01:58 am
Thank you - These braided hoses are Summit brand with Summit AN fittings, lot cheaper and probably from a reputable company like Russel.  The rubber part is Russel.  For the brakes, used Cass at Dr. Diff - budget, nice and bolt on.

Citron - Thank you -

Found a buyer for the 470 sooner than anticipated, so this accelerated the removal of the B motor.  Since I had a little money, thought I would do the swap of the 5.7.  What I have learned is there are many little nuances with this swap, all of which are easy to over come, but definitely makes for an a little of a learning curve.

At this time, it is almost ready to fire, should be smoke and flames by the end of the weekend.  There are many learning points, the largest in my opinion are my transmission (GM TKO 600), headers (TTI 6.1's),  and the 2012 5.7 itself.

Transmission - well, what I have learned is the GM TKO takes more understanding than a Ford TKO.  Apparently Fords are the common swap types, with pilot bearings and bell housings a little more readily available.  In the end, I had to order a special bearing from Silver Sport Transmissions and a bell housing which will only use a 130 tooth flywheel.  Accomplished, but.... probably easier ways out there.  I used the clutch and pressure plate from my 470 and a RAM aluminum wheel.  I will post results later. 

TTI's are awesome - but TTI's and Gen III's, well be ready a slow going and tight installation process. Nearly all bolts I needed to install from underneath the car with 1/4 sockets and extensions.  Once I had headers on, I had to install the crank trigger sensor - really not fun.  This really was the longest part of the install.  Passenger side slide right in BTW, drivers side was generally easy.  Starter is not trapped like BB's and well - #6 plug, no worries now. 

As for the Gen III (2012), lighter, more sensors than old people have pills, and still learning acronyms like VVT, MDS,  variable intake sensors, and MAF vs MAP.  Well here is a picture of it installed.  Also, this is a CL purchase, so the  person I bought this from said "I swear this only had 60K and was perfect when pulled."  Will let you know when I fire it this weekend.

Worked through some of the small stuff such as tucking wiring up, installing an LS throttle cable, and various other items to get it fired.  Nice thing is it fired real fast - like nearly on the first crank.  Since I don't have a radiator, only ran it for a few seconds.  Sounds good, I have an issue with #2, I am thinking an injector is down.  Intake sat around for probably a year or so with fuel in it and fuel port not covered, so....  Also, AIT is not hooked up, apparently this is a deal in the EFI world.  Ordered a Spectre system from Ebay, so again awaiting parts. 

Cool thing is this has 70 pounds of oil pressure at idle and I hooked up to TunerStudio on my MacBook.
Getting a little burnt, so will be nice to take a break as I wait for parts, will keep the progress posted.

Casbah, been checking out your '70 Barracuda, EK2, no frills build. I see you chose the 440 to suit your needs, good choice. I really like the " Vitamin C" color on your Barracuda, my '70 Challenger also came K2, Go-mango from the factory. Just like the color, mine will most likely stay this color. SE trimmed outside and black SE trim inside w/ Rallye's at all 4 corners. Like it just the way it is.

Post by: Cazbah362 on July 19, 2017 - 12:46:46 am
Cudakiller - thanks, easy is questionable, it is taking its toll on me, I am a little burnt right now.  As for cheaper, I would guess where you are starting from could make that difference.  If you have NOT purchased all your parts, I would say cost would be close, less computer, it is the expensive part.  But I see there are many options other than the Gold Box.  I must say Mike who sells the Gold Box has been awesome for tech support, so I would do the Gold Box again.  I have called him with random stupid questions and he has not hesitated one bit - AWESOME guy and product!  My fuel pump wiring was set up for "on switch" functionality, I could not figure out the on ground for the Gold Box.  Called Mike, he walked me through it and poof, fixed. 

/6 - Thanks, yes actually this car is a factory EK2 car as well, kind of cool.  And I am with you, no frills, let's get it done. I actually had a 470 (B motor stroker) which was a lot too wicked for normal street driving - but actually did it pretty darn well.  I can tell you, I was not going to sneak out at night or sneak in in the morning.  Wife actually told me I could not start it before 9am or after 9pm, 8pm work/school nights.  I changed mufflers from the Summit 2 chamber to Summit turbo's.  On the Hemi so far, the Turbo's actually sound nice.  She might let me out when the lights go down now?  and I agree - I too like them the way they are, post a picture of yours, or PM with it.  Sounds like my kind of car.   

Rack time -

Thanks 70Chall440 - It has been a learning experience for me. 

The following is to help the next persons who do a similar build.  I had a very hard time finding credible information on the internet related to radiators, hoses and what worked. With that in mind, maybe this will help the next person.  Again, my build is with a Gen 3 LX motor (2012 Challenger), manual (Non-vvt), and I had a 26" brass factory big block radiator originally with a passenger side 1.5 upper and a driver side 1.75 inlet lower. 

To start changing things, I purchased installed a Champion CC375B radiator.  This appears to be the same size and dimensions as my 26" brass factory radiator, so my justification for doing it is - its lighter, modern and easily adapts dual fans.   When I purchased this, I talked with LedFoot racing asking for a "swap radiator," the CC375B is what they recommended.   With that said, I asked what hoses they used - response was - I don't know, go to a parts store, measure and check.  I called Champion, same general response.  I them called Bouchillon - well that response is a whole other story, and not pleasant nor helpful. 

So after going to a parts story many times, here is my solution:  The upper radiator hose I used was a Gate 22900 - I trimmed it about 6 inches and perfect fit.  Lower hose I used a combination of the old BB upper hose, old factory 5.7 hose attached to the motor, a 1.5 to 1.75 adapter\reducer, a piece of 1.5 aluminum radiator tubing.  I spliced them together using the 90 degree 1.75 portion of the upper hose from radiator to bend, then trimmed 5.7 hose back, spliced with pieces of aluminum and 1.5 adapter\reducer.  I get it this is a little "June Bugging," but it worked for me, only costing me the price of aluminum hose and adapter ($5, and $8 respectively).   

As a side note, I understand an SRT lower hose may work.  I went to dealer, but one was not available.  Down the road I may order and attempt to verify this to correct my "June Bug" approach.   

I do hope this helps someone else down the road.

As a side note, I understand an SRT lower hose may work.  I went to dealer, but one was not available.  Down the road I may order and attempt to verify this to correct my "June Bug" approach.   

I do hope this helps someone else down the road.

Finally nearly to the point where I can take her for a shake out run.  Exhaust is on, fluids are filled, and the thing idles at about 850rpm.  Right now I am awaiting LeFoot's shipment of 12" fans.  Once out on shake-out run, I can check and validate some concerns. 

First concern is the alternator.  To put a 2012 alternator in these, you need to use the pre-70's voltage regulators.  I have a 220 alternator, which concerns me a little.  I have done some wiring modes, like amp meter bypass, headlight relays, and minimization of other accessory areas. I have also thrown multiple body/frame/engine grounds to help out.  At the trunk mounted battery, it starts with about 13.8 and works it way up to about 14.2, this creep concerns me.   

With this exhaust (TTI 5.7 headers, 3" with X-pipe and Summit Turbo's), sounds like a modern car - subtle rumble at idle, roar at WOT (which comes quick, definitely need a rev-limiter), now the wife may hang out with me?

During shake-out, I will also do some tuning, seems really what shake-out will be.   The 6.1 tune worked well for start-up, but now I am noticing small things like idle, a little air stutter do to the 92mm, and to work on the fuel MAP better.  Also, the 6.1 did not have VVT, this motor does, so need a few passes to check, change and verify.  I am going to mix some 100 octane with 91 to bring up octane.

This is the plan as of now, here is a picture of the engine bay - Also need to do some cleaning, picture makes it look a little dirtier than really is in person - I will work on that.

Excellent progress, had me thinking about changing my route with my Cuda and going to a modern 5.7 or 6.1. I have too much time and money in my 416 and EFI 6 Barrel, so I will stay the course.

I am sure you will be smiling during the shake down drive despite any bugs...

Finally had a chance to install the fans and do a quick run down the highway.  First, I noticed the water temperature sender was way off from Dakota Digital, this discovery was while driving.  Due to this, I simply turned the fans on and headed home.  Once home, I found the sender unit was NOT a GM but a >85 Chrysler type.  Since the engine did not "officially" warm up based on the computer standards due to this issue, I had no tuning.  At home, and once warmed self tuning came on and only got to work on the idle. I also set the RPM to 6400 not 6000, I will need to wire in the shift light to the Dakota gauges. 

Before the run, I noticed a water leak and small oil leak, after the run - no leaks and plenty of fluids still in the proper place?  Hmm - I really doubt I am that lucky.  I figured the water leak came from the engine heater cross-over.  I simply crossed the left and right banks with heater hose from the big block. 

Also, the alternator I was quipping about earlier.  Well it spiked to 15, dropped to 13ish, bounced for a while, then settled at 12.4 - looks like i will get to invest in a Napa brand really soon - luckily I will have a core and bonus - I can clean up the fine metal work I did while clearing it as described earlier in the post's.  But driving it until it drops -

Its Hot August Night here and I will get to make a showing!! Looking forward to it!

Well weekend was semi productive, had the opportunity to take the car out for a few shake down run and to a local car show.  Car ran great in town as well as down the highway.  As I learn to use the self-tuning side of the software and apply the settings, the car really starts to become much more enjoyable.  Power at the low end is phenomenal and not what I fully expected.  With the BB, 1st gear was generally non-existent.  Now 1st gear allows some "driving" time and there are definitely not as many shifts.  I can down shift on the freeway between 4th to 3rd for power. 

One thing I spoke about in my earlier post was the aluminum flywheel.  Right now I am not fully sure.  initially with the tune not correct, it was a little bit of a bear not stalling or driving when cold.  As the tune improves (fuel map), it becomes easier to drive and enjoy.  So more to come on this. 

Another item is weight.  I am guesstimating I reduced about 200 lbs with the swap, please note this is not all "motor."  Things like aluminum flywheel, aluminum radiator are included in this guesstimate. The BB had iron 452's etc, so there was some weight on that beefy pig.  Things I noticed so far is the ride height of the front end which is about 2" higher and the steering.  The nose moves a lot easier and is way more nimble.  With this new found height and agility, need to do some adjusting.  This brings me into plans for the future, so here they are:

1.  Back seat - need to wrap the lower seat around the roll bar, deadening material etc
2.  Radio - with the new exhaust, I believe we can now enjoy one
3.  AAR stripes
4.  Rear view mirror - any have one for sale?
5.  Wipers arms and blades -
6.  Digital headlights
7.  AAR/Rallye lights and that little plastic piece in the lower grille?
8.  Wheels and Tires - really like the year one 17's soooo and like the new Weld 5 spokes - going to be a battle
9.  Engine - Possible Arrington 5.7 heads with a 270 cam (I found a 2012 truck engine, its now in my garage for "research purposes")
10.  Pro-charger
11.  Dana?  maybe, I may look at some form of traction control through the computer.  Older 9.25's have toner rings and I believe the Ford 8.8's do the same?

Always open for suggestions -

Well here are some pictures of the car at the show this weekend

Just re-read your thread, quite a journey.

What controller/computer are you using? I have a Holley system in my Challenger and will be using a FAST system in my Cuda and like you have and am learning the EFI lingo.

As far as your AAR driving/road lamps; get a set of KC 4" lights, they have a black housing and blend in nice. I bought mine from a local Autozone for like $39. The original AAR/Cuda lights are 4" but they don't put out crap for light. Of course there are a number of other 4" lights out there ranging from LED to Halogen. I made my own brackets because I wanted my lights on the outer edges of my lower valance.

70 -  I am using the Hemi Gold Box, pretty cool system, lots of options and support from Mike the owner.  How do you like the FAST?  that was a consideration at one time, and which Holley?  As for the lights, I plan on using your recommendation.  I already have the brackets installed, just need to do the lights.  Thank you for the information and help.

I have to look up the Hemi Gold box. I cannot comment on the FAST system yet bc I haven't gotten the car together to see how it works. I am using the Holley HP system with the F&B 6 pack on my Challenger. It took (and is taking) some learning but it is good overall. Like your system, it learned more as I drove it. I think it still needs some more but I have refocused on the Cuda.

I was a bit concerned with the FAST system after working with the Holley system; the FAST system I am using is the FAST EZ and I just have the hand controller (no laptop needed). I was concerned because after seeing how the Holley system worked I wasn't sure the FAST system would work very well. However, I just found out that FAST has a new ECM that you can interface with a laptop, so if I don't like what the EZ does I have options.
