I figured this question would be best answered by GM. I'm interested in someday getting this mod done seeing as how the intake and heads seem to be the RWD 3.4l engines weak point. I have read in a few different places about the intake and aluminum heads from the 2000's pontiac grand am gt and how they are pretty much bolt-ons for the RWD 3.4 and how they flow MUCH better than what comes stock on the RWD 3.4l. But when I get a mod for my car I want the best.....so is there a better fit? When I say better fit I mean better air flow and more power, minimal modification to get it to bolt on.

 

not really a question for the ASK GM section. you will get better results in the v6 tech section.

 

cool, you would know best.

Thanks

 

you want the heads and intake from a 3500 Malibu or g6 (other cars too) pushrods from a 3100 corsica (others too) you want the head gaskets to match the pistons (3400 pistons 3400 gasket/3500 pistons 3500 gaskets) theres more i just dont remember everything off the top of my head
