Compression Calculator

Just so you know;
I ran 11.0 Scr with those Eddies and a Hughes 223/230/110 cam, and got about 180psi CCp; and it burned 87E10 at 34* PowerTiming, no problem. I loved that combo and would still be driving it today, if the lobes hadna started falling off the cam.
That cam also made funtastic fuel economy when geared 85=2100.
