FH Valve Springs
I have another question for the guy's that run, hotter cams.
What is the minimum, installed pressure and the maximum open pressure, for a .375, lift cam, that will turn 5500 rpm?
Pictured is Isky's valve spring spec's, are they good for 5500 rpm?
Also, I have read on this forum, that you have to watch out for higher pressure springs, because they will wear the cam out.
What is the reason that the cam will wear so fast, with what I think are fairly low pressures. In modern, OHV valve engines, we run 300+ lb, open pressures, w/o any cam failure issues.
Thank you,
Frank
