If it’s still apart, measure the upper bearing surface on the crankshaft with calipers or a micrometer, just to be sure. I just had a ’55 15 that had zero rust in that area but the journal was .002″ worn and the bearing it rode in was worse. There was so much slop in the upper bearing that it was throwing the points out of whack and the engine wouldn’t run right, because of that. I’m ashamed to say that I put mine all together, thinking the bearing was fine, just because there was none of the usual rust. After figuring out the problem the hard way, I had to take it all apart, again. Yours is probably fine; but I am just trying to save you that potential grief.
Long live American manufacturing!
