The old man is putting his 512 together....he installed the cam bearings....cam wont fit....both the new and old cam wont go in easily. I thought maybe a bad set of bearings....so we knocked them out......used a different tool and a new set of bearings....I even had him 800 oil sand the bores to make sure they were clean......guess what....same issue...this time we're checking figment as we go. So far its #4 the 3 hole bearing with an issue.
You guys ever ran into this?.....I've NEVER had this happen in 30 years of building motors.
