Cam Question

What year stock compresion engine is this. OR what is the actual ratio?

IMO, It would be a little soft on the bottom end unless you up a low 8-1 ratio engine to a 9-1 or 9.5-1 ratio.

Upping the ratio is more so a bennifit for street driven cars because it regains the lost torque with trhe bigger cam.

The bennifit up top in the rpm range is huge when you compare.

Milling the J's would be a big help.
