We will be degreeing the cam tomorrow. Ed Curtis has already address excessive cylinder pressure with this new bumpstick, it will handle 10-1 CR and boost no problemo

Cam specs you posted along with the MP122HH...
Keep the awesome pics coming!

That should go pretty well with the low boost numbers. With all the parts you've picked I'm guessing that the 2.8" pulley should net about 10psi@6000rpm. The torque off idle should be rather impressive though.

I remembered about the 122H. I was going from the numbers that the GTO put down. That was a pretty much stock 5.7L with a 2.9" pulley. Between the extra cubes, cam, headers, heads, etc, I'd expect at least a 1-3psi drop in boost over the GTO which would put him in at just over 10psi.
