Cam for a 318
yep, that's just me. There is no drawback to lift and no reason not to open a valve at least .500.
Look at any roller cam that is comparable to a racer brown, same duration, same LSA, WAY more lift.
Why would you not want to open the valve?
Ex.
[email protected], .509 lift, 108 LSA. vs.
[email protected], .650 lift, 108 LSA.
