Yup. I have the GMPP version of the Crane Golds installed on all three of
my SBC cars for several years; never had any significant problems with false
knock. Lifter preload is zero lash +1 full turn. Stock GM lifters. Mild
cams (ZZ3, Crane 2033, etc.). I usually set the valvesprings for 130 lbs of
seat force. Had a *slight* bit of KR at low-mid RPMs with the Impala that
would only last a couple of data frames, that I eventually decided was false
knock. The LT4 KM cured that.
P.S. Cornel, would you please disable the HTML in your emails?
