Bob should have been able to throw his cam in from across the room ![](/ubbthreads/images/graemlins/shruggy.gif)
I'm going to guess difference in measuring tools .
Bob I would take the shop up on his offer , he should have asked you for a cam when you dropped off the block for the build I think. Has your cam been checked to see if it's bent ?
Those clearances dont add up... that would be a TON of clearance on each journal
My guess would be someone is using a micrometer and someone else might be using a vernier caliper or a poorly calibrated mic.
