Hi guys. My '58 Delray windowed-delivery project is finally getting close to the end, and I'm putting together my 348 now. Just a stock-type rebuild of a '59 348, cast .030 over stock pistons, stock cam, adding 3x2's though. Anyway, last night I tried to slide the cam in (Sealed Power stock replacement), and when I get to the point of it entering the rear bearing it gets tight - it goes in if you twist it while pushing it in, but it's tight in that rear journal - doesn't want to turn without significant effort. Thinking it could be an issue with the cam, I tried installing the original GM cam - same thing. I removed the rear cam-plug, and tried just sliding the rear journal into the rear bearing, but it's not going to go in without some effort, so I didn't force it. The cam bearings are from Show Cars, and they said that they are most likely Clevite or Durabond, and that they've never heard of an issue like this or had a set returned. The bearings were installed by the machinist who did the bore/hone/etc., and it's the grooved, 3-hole bearing, and the holes look to be lined up properly.
Any ideas? I tried searching the forum, didn't turn anything up.
Thanks!
