Took my short block to a friend's shop to have my Comp XE284 installed and degreed in. Had to severly muscle the cam past the 2nd, 3rd & 4th cam journal openings. Once installed the cam was very difficult to turn with a wrench. Dan Whitmore drove over to take a look and the cam needed to come out as it would have wiped cam bearings instantly. Dan "miched" the cam and all journals were dead on. Used a dial bore indicator and some journals were .002/.003 undersized. This was a rebuild of a 455 that I had in operation previously and cannot for the life of me understand exactly what changed....?
Other than Dan's assumptions does anyone else have suggestions on what could be the problem?
