Your kidding right??
I have built many a 5.0/302 block and we where breaking them at the 475 to 500 hp level.
he'll be lucky if he even see's 400hp out of it if its a stock motor plus lowering the compression to 7.5:1, but i can see where your coming from if he builds it up for the strip she'll pop. plus i said a max of 12 psi.
