What could cause this? 360 problems ####update####
I built my first piston stop in about 1972. NINETEEN SEVENTY TWO and I still have it, why? Because I started finding stuff like Fords (yeah I built one of them, too) with balancers that slipped, and I've found a few Mopars that slipped. MOST OF THE MOPARS that I've run across that were wrong on the balancer mark were newer/ older engines with differing timing covers, in other words and early engine with late timing cover or vice versa and now the marks just plain way WAY off. So, "piston stop" to the rescue
Then I started reading about cams with built in retard/ advance from "straight up." This actually started happening in the "smog ere" back in the 70's
Then I started reading about manufacturing tolerances that can "add up" in the wrong direction
Then I started reading about Chinese/ other imported parts that were just plain out of tolerance
