engine noise

Rob,my learning curve,reflects those comments. Anymore, there Is "no safe,sure bolt in " in aftermarket parts anymore. There is a reason,why people run stock style equipment , unless looking for serious E.T. numbers.

I have gotten to where if I make s non stock cam swap in any engine now, I measure for correct pushrod length.

Cam makers are stupid secretive and most times will not tell you if their cam is ground on a smaller base circle. You have to measure.
