360 .060 overbore too much ??????

This is what I seen and or read in the past. 71'-73' 360 blocks where cast the same as 340's so there much thicker. I've seen a few 71'-72' go to as much as 4.100" without issues. I've talked to other mopar builders and they've seen 4.125" bores with no core shift. I do believe after 77' it's a crap shoot on thickness. I had a 85' 360 in a friends duelly fresh rebuild bored to 4.060 and it used oil like crazy to the point where I knew something wrong. The motor was built by the same builder that does my race motors. He sold that beast no telling what happened. Sonic check everything as others have suggested and you'll be in a better place.
