Hey all Iím looking to build a 383 and plan on spining it to about 6500 rpm with a rev limit @ 7. Iím on a budget and plan on putting a 100 shot on it and no more than that. Itís going to be a street/strip vehicle. Iím looking to make 400 NA and 500 on the bottle. Iím going to use a forged piston with Gm P rods and a cast crank. I would love to go all forged but its either forged bottom and a cheaper set of heads or good heads and cheaper bottom. Whatís some of your advice on this matterÖÖ.
