Compression Ratio Question

Packin,
I agree with the majority of the guys this will be a great build.
I am originally from south florida and you might want to rethink a few things.
93 octane is not available nation wide, however 92 is. So engineer for that, I am living in Texas and here we have 93 but I am still building for 92 because my car will see alot of highway miles.

Second the cam could be a little bigger to take advantage of the increased volume you will have.Your compression/octane requirements are governed by what is called 'Dynamic Compression' This is calculated by taking into account the 'Static compression' of your piston/stroke number ( say 10:1) and factering in the actual closing of the intake valve. This is why your DC is changed depending on the cam/piston combo you choose.

If you figure out you are on the edge of reasonable compressoin numbers you may want to concider coating the top of the pistons, chamber and the face of your valves with a thermal barrier.
