[Bruce Wilcox (EUS)]

Hi Mike,

I have a combination ( 87 IROC, manual 5 speed ) similar to yours. My
compression ratio is at 10.2:1 (AFR heads) and my cam is 214/224 at 0.050" &
0.495" lift hydraulic roller. Very similar horsepower and torque curves. If
you are interested, I can send you my BIN file.

Best Regards,

Bruce Wilcox
