Big Bill I did use plastgauge on the front main bearing ( only cause I ain't been back to do the rest) I used the .002-.006 size. The front showed to be less than .002. The rod bearing was obviously the wrong size but main has std stamped in it just like the rest of em.

Jase, go up to JP Salvage and get another crank shaft and fix it right.

That's what I'm gonna have to do. At least I'll end up with a new engine this way.
