Thanks for the quick reply Dave. I was already out taking the inspection plate off hoping I might find something that doesn't look right. I remember something about an oil line under the inspection plate, but I've looked at so many old blocks this last year, I don't remember what this engine has. I'll let you know.
Casting number looks like 3769716. Another post on this forum led me to the inliners site that doesn't show a 376 number, but shows 8769716 as a 58-62 Chevrolet 235. So I'm assuming I'm just not reading the casting correctly.
The machine shop that did all the work on my block and head installed the cam bearings, and I don't remember looking at them to make sure they were installed correctly. (Heck, I probably wouldn't have known if they were) I'm hoping not, but right now thinking I'm going to end up completely disassembling this puppy.
