Post Intake Manifolds ?

I just drop of parts at a machine shop to build a Chevy 383 Stroker. I have World Sportsman II heads,Pertonix HEI distributer, Holley Street Avenger 770CFM. TH 350 Trans with 2100 Stall Converter & 3.73 Posi rearend. This will be going into a heavy 4000# 1976 Monte Carlo. I know I need a lot of low and midrange torque to get this beast moving. This engine will be for high performance street use. I will be using a Hydraulic Cam since a Roller is so expensive. According to the Engine builder a cam of about .500 lift should be used. I do not know the exact cam specs yet. As always thanks for the help. Joe

My question is, should I use a dual or single plane manifold ?

A dual plane will give you much more bottom end I would go with the dual plane if I were you

I have a similar combo in a much lighter vehicle (2660 pounds). 350 small block, 190cc AFR heads, Edelbrock RPM Air Gap and Holley 770cfm Street Avenger. Comp Cam 280H .480/.480 lift. 3.80 rear gears, 1800-2200 stall and 350 trans. Running 28" diameter rear tires. Runs very strong, but due to the light weight I could use a little more stall.

As to your question; I'd suggest that you stick with a dual plane intake for the street and if you use an Edelbrock get the RPM or the RPM Air Gap.
