The 360 build that has more turns than Willow Springs

The guy doing my block had mentioned that all Chrysler engines need this treatment - even LAs. Apparently Chrysler cam bores weren't the best. Do you have a spare cam? I was thinking about making one of those myself. I think I've got a spare floating around somewhere.
I haven't had a small block with that problem in 20+ years. Only big blocks. If a shop pounds the bearings in with a expandable mandrel and a hammer, THATS what causes it often times. The use of a hydraulic cam bearing tool eliminates most of those problems.
