It can be...

I believe the runout limit is 0.003". You measure that with a dial indicator, located so the dial rides where the cam support plate bushing 'seat' is located on the crankshaft. They say if the runout exceeds that, there will be significant interference which will make it noisy. There are over/under sized gears, to accomodate the amount of clearance needed. Some one else will have to explain that part tho.

CroK and to the OP I appologize...The information I had posted is INCORRECT. CroK you were correct in that the INA bearing is also trouble. The upgrade inner cam bearing is the Torrington full compliment (cageless) bearing. CroK I think you and I share the same Roll-a-Dex.
