Just a guess. Since I am not familar with your heads and how they flow and whatnot. But I would say it would easily make 375hp? Maybe more?
Would be a nicely stout engine most definetly. If you chose a different cam I think you could make more power. But if you are decided on the cam or already have it then that will have to do. My choice would be a Comp Cams Magnum 280H with .480 lift. That one works REAL good in my buddys Camaro that we built. Of course it is a 355, but never the less the power would be pretty similar. Camaro does 7.20s in the 1/8th now. VERY stout small block! Check it out... lata CHRIS

Just curious...But what rods are you going to use? If you are using some good rods you might be able to go with a larger cam and use that Upper RPM potential of the 327. Say something that goes from 2500-7500 rpm!??!

Thanks for the info, I was hoping for about 350 horsepower and changing a cam is not a big deal.

I can't figure out how a piston manufacture can list a compression ratio with a given piston while not knowing what combustion chamber the heads are, if the block's been 0-decked, and what head gasket you're using.
