This is one of those deals where there is no wrong answer. It's a little like picking a color, it's a personal preference thing. I really would like to have a hot 318.........
Good luck with you Hot Rod, sounds like it's going to be a very sweet build!

I've just pieced together a budget 318 out of spare bits I had lying around and bits I picked up cheap.
Cam is Crane H-278-2 with rollmaster gear set at 2deg adv and comp lifters.
Intake is edelbrock performer topped with edelbrock 1404 500cfm performer 4bbl.
heads are 318s mildly ported and milled to give a true 9.8:1
Exhaust is a set of Patriot 1 5/8 primary pipes into twin 2.5" press bent system.
HEI dizzy.
Not up and running yet but i'm hoping for around 280fwhp.
Burnouts are cool but Traction is the Action

I have a 87 W150 with a "mild" 318. I used #302 heads. Had 1.88/1.60 valves installed, I did the bowl blend, and gasket match my self. The block was bored 30, and filled with KB pistons. I used a comp XE262H grind with 340 springs and some proform 1.5 roller rockers. Edlebrock performer intake that I also gasket matched (heads and intake 4 barrel sizes), with headers and Ede 600 cfm AVS. The truck was an auto that I converted to a NV 4500 5speed, and It will bounce your head of the back glass on 2-3 shift with 33x12.5 inch tires !   :jumping:

Your build sounds very similar to what I'm considering if I decide to stay with the 318 in my 73.  Already have a set of 302 heads and LD340 intake.  Only difference is I was thinking 650 on the carb and have a set of hipo exhaust manifolds out of a 70 340 car.  That or build a 340 for it and just keep the 318 stock in the corner of the garage.  Decisions, decisions....

Continuing the 318 discussion.  I have a 73 cuda with a stock 2 barrel 318, 904 trans and 3.55 trutrac.  The car has dual flowmasters for exhaust and everyone that hears it says it has a little cam although I have not opened the engine to find out what it has.  Eventually I will build a new engine for it but I'd like to bump up performance on the 318 for now with just bolt on's. 

I found this intake and carb for sale locally.  Would this fit?  Would it be worth it?
thanks,
Dave

It would fit, but wouldn't be my first choice.  For one thing that manifold has larger ports than your 318 heads, but will work OK.  As an economical choice it wouldn't be terrible assuming you can just put a kit in the TQ and make it work, but more than likely that is going to be a little too much carb for a stockish 318.  First choice for a manifold would be an Edelbrock LD4B if you can find one they usually go for around $125-150 or so.  A little less would be a used Edelbrok Performer which I've seen go for around $100.  Carbs are harder to get one used that are truly bolt-on ready so I'd go new or rebuilt.  New Edelbrock Carbs in the 600-650 cfm range can be had for $250 or so with manual choke, maybe around $300 for electric.  Other than jet changes you wouldn't be looking at having to rebuild it, etc.  So any of these combinations would be a lot more than your $160 option, but would be ready to go compared to your unknown used TQ.  If you're OK with rebuilding the carb and need to keep the price around $200 including rebuild kit, go for it.  If you have more $$ and want something more ready to go out of the box, keep looking.  Don't forget kickdown linkage (if yours is an automatic) have to be tweaked or changed out for a higher intake.

Something in the K54/K56 Engle range would be great for a warmed up 318
 maybe I missed the PM ???

I was known in my area in the 80's for doing just that.  I would run  a few mods on the motors along with a 400 hp nitrous kit.  I never had a bottom end go out.  I would loose a piston normally.  I broke two camshafts in motors.  It is amazing what the 318 will handle a 1/4 mile at a time.

I Put a 650 cfm Edlebrock new in box off ebay for cheap on dads 1970 318. with an Edlebrock intake I bought for $20 from a friend. Dad said it never ran so good, even from new when he bought it. Has quite a bore job (not sure if it is .40, .68. Or .80 seeemed like a lot when I picked up the motor in 1995. This last summer I replaced the junk home made exhuast with a huge kink oved the oil filter with a set of Headman headers for about $160. It did have decked heads as well, and I think a mild cam. It has a 3 speed manual geared very low, and will consistantly chirp the tires at 60mph going from 2nd to 3rd gear at 5500 rpms. Car is my daily driver in the summer, and has many trips to 6k since the rebuild in 1995,and uses no oil between changes. Hope this helps, been told the old ones made more power, but I don't know for sure?

just my two cents but the magnum heads breath better the the L.A stock heads and you could just a pair pretty cheap only ting is you have to run a magnum intake as well you can still be carbed and all that

this thread is old that 318 is probably land fill or boat anchor by now.
