This is copied from the original post, very confusing.
1967-UP CHEVROLET V-8 396 THRU 454 CU.IN.
MODERATE COMP. ONLY, GOOD UPPER R.P.M.
TORQUE & H.P., HIGH COMP. RATIO REQUIRED
Moderate comp only, then high comp required? wt?
I'd go with the springs recommended from crane they know whats best for their cams, or go with a comparriabled set with them same seat pressure, same installed height and coil bind.
Goodluck, Charles
