Yes it will bolt up but use the 305 intake gaskets.

I wonder if it's possible to mill one of these down and convert to a 4 bbl setup? Holley Street Avenger, Rochester Quadrajet, or Carter AFB??? Last edited by Chuck78; May 23rd, 2016 at 01:37 PM. |

Here's some pics of two 4bbl manifolds I built, one uses a spread bore adapter so Quadrajet can be used and the other just uses a square bore spacer, both manifolds were milled down and the bases were opened up. The Magnum manifold already has 4bbl plenum in it because GMC actually did offer a dealer installed 4bbl option so the 2bbl version of the manifold was just cast with a different top base

Well it's all bolted up and the motor is running like a Champ! Drinks the gas with No issues and pulls darn well. Really happy with how it turned out. Super easy to start compared to before to.
