Formulajones,
Call me crazy but I still hear the knocking noise.

Prior to me getting the motor back, Paul spoke with the guys that worked on the motor and he cosigned everything that was done. There were experienced hands in Arizona that touched the motor and there were experienced hands that touched it here.....same knocking noise. Of course you're going to grab at the one guy that believes the knocking noise is lessened with more rpm...all the other guys that have spent more time with motor disagree. I'm at a disadvantage because I just don't know anything about motors....but my hearing is good!
