Not Ranked
It's a Comp Cams 33-000-9 which probably doesn't help. I can provide the grind card if more info is required.
Gross Valve Lift: Intake: 0.645", Exhaust, 0.635"
Erson Lifters 1.76 ratio
Lob Lift: Intake 0.3670" Exhaust: 0.3610"
Intake 0.367" * 1.76= 0.645"
Exhaust 0.361" * 1.76= 0.635"
That seems to be the right calc since the result equals the gross valve lift. This cam must have been ground for 1.76 ratio rockers?
