Yesterday I sold my 82 cj7 (which was inside a shop building that burned down) however the guy didn't want to mess with the motor. So now I have a 4.2 that most likely has good crankshaft, rods, etc. So I started today looking into a stroked 4.0 first question I have is about pilot bearings one article which was pretty old briefly mentioned that pilot bearings changed between the 4.2 and the 4.0 and they had to have the "newer style machined to fit the 4.2 crankshaft. Any insight on this or some good references to check out? Thanks in advance!!
