360 build info

A high 12 sec. goal is sounding a little lofty.
Maybe a 14 second bracket will be more realistic.

What type of power can one expect to pull out of a 360 w/ flat tops, factory J heads w/ no machining for fancy valve parts? (springs, port, etc)

Back to static compression.
I have top of piston average of 4 different holes.
32.25cc (with head gasket thickness)
Once I have cc'd the head chamber (w/ spark plug in hole using plexi-glass cover w/ 2 holes drilled) How do I then figure my compression?

What is the correct equation to use?
