I just got a short block off a member on here that was built for boost. It is a Iron truck block with a 4.00 bore so it is still a 364.

I also bought a sheetmetal intake from a member on here a long time ago that was built for LS3/L92 ports. I was thinking of using a set of the LS3 PRC heads since they are an aftermarket casting with a thicker deck compared to stock ls3 castings. The only question I have is, are these heads durable enough to withstand a decent amount of boost?

Has anybody used them in a boost application?

Head studs, a good tune, and ls9 gaskets and youll be able to push that setup pretty far

I wouldn't consider 15-25psi moderate boost....

With ported LS3's and the right turbo you can make around 1000rwhp on 15psi with an LS3 intake.
