i am working on a 455 i recently acquired,tore it down to the shortblock to see what i had. everything looked good just going to change the cam and reassemble. ordered a new crower wont even go in the block! stops at the second bearing. so i did some searching on this board found a bunch of threads. so far i pulled the front 2 bearing and replaced them because the #2 looked crooked. no better so i cut some grooves in the old cam to true the bearings.the new cam goes in now but is still hard to turn. so what do i do now? keep working the tool? i read in some old posts the cam bore is to tight and the root of the problem. can the bores be honed with 3 stone or a ball hone with a drill motor? polish the cam it measures 1.900 the old one is .001 smaller. what really sucks is i now have to disassemble a perfectly good shortblock to clean it. need some advice from those that have been there done that.
