I am trying to determine what this engine combination will put out. I recently purchased these heads and a friend says I should have 373 hp @ 6500RPM, 303 Torque @ 6500 RPM which is a bit disappointing. This is my first build up. Does anyone have software or can give me an idea on what this should make? I am considering selling the heads and buying aluminum to handle more compression. With these heads I will have 9.72:1 compression, but I can bump it up a bit with a felpro 1094 steel shim gasket (compressed thickness (in): 0.015 in. and compressed volume (cc): 3.200cc)
. Any/all help you guys can provide is greatly appreciated thanks.

I do not see an engine combination similar to mine. They have a couple stroker motors running the same cam, but different heads, larger cu in, etc.

What kind of numbers are you looking for?
