It's a little bit complicated running boost in one too because there's a bit of a shortage of good pistons, I could use acl flat tops for 8.3:1 I think? (I Forgot) : ) or bore it for Chev 305 flat tops at 7.3:1. But you can also then get domed and dished pistons with the 305 ones and better pistons. Either way it should go 500hp on 14 psi but 10 psi maybe a bit more sensible.

I did some sums just out of interest with a 253 and injected heads and banana manifold and it makes pretty much exactly the same peak hp as an injected 304, the power curve isn't as fat down low because torques not so good but it would still make pretty fast times really, ie smash a V6 (easily) :)
