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 Their website and cam card directly contradict each other. |
Here's Crane's webpage about the 99876 springs:
http://www.cranecams.com/?show=brows...&lvl=3&prt=123 I have my springs at 1.905 to 1.965 installed height. Maybe I should shim all of them closer to 1.900 to get few lbs more of seat pressure? |

i would go heavier than (needed) to get the job done to be safe
i wouldnt want to float a valve kiss a piston,and shuck the valve keepers - resulting dropping a valve,and ruining a motor for the few bucks buy what you need valve designs are so a weak spot in a motor |
