My new setup will be:

-Rebuilt 350 bored .030 over (355) with 10:1 compression
-AFR 195cc heads
-Performer RPM Airgap manifol
-Comp Xtreme Energy 08-432-8 hydraulic roller cam (282/288 dur, 230/236 @ .050, .510/.520 lift)
-AFR Hydra Rev kit
-Holley 700 DP carb
-MSD 6AL box with MSD adjustable distributor

-700R4 trans with an ACT 9.5" 2600 stall converter

-Spohn subframe connectors
-Spohn lower control arms and reloc. brackets
-Spohn adjustable torque arm
-3.73 Strange 12 bolt rear with Mickey Thompson slicks

Do you guys think 12.20-12.30 is achievable with this kind of setup? Weight is stock, probably around 3500 pounds. Any comments, criticisms, or suggestions would be greatly appreciated. Thanks in advance.

 

More stall less weight

Sounds like a badass setup. A friend of mine ran a setup like that in a 70 Camaro. It ran a victor jr and a really big flat tappet cam tho. It lacked on torque, but it managed some 12.4X's on slicks. With a little more stall i think you could probably go either really really low 12's or high 11's. Also my same friend switched from a Holley double pumper to a mech. secondaries speed demon and dropped from consistant 14.55 to 14.40, so thats something to think about there.

You'll need more cam to go low 12s. Take it to the track to get some baseline runs in and then adjust from there.

 

I think you should get to your goal of low 12's. I have a similar setup w/ a 383(see signature) and have run very low 12's with poor traction. My cam specs are : 280/288, 225/230@.05, .525 lift. Like someone else said you might want a little more stall and also you might want to do some things to lighten the car a little bit. Sounds like a good combo to me.

 

I would go with more stall, but I want to keep this as streetable as possible right now. It is a 9.5" converter, which by itself is a huge improvement over stock, plus the fact that I am still using a stock 84 700R4 trans (with a Transgo shift kit and an external cooler) and I want it to last as long as possible. I don't need the extra heat of the slipping of the converter, since I drive it down the road. I don't think it's too bad of a stall either, considering the cam I am running. Thanks again.
