The oil pump is the one that was in the engine when I removed the engine from the car the first time. Now...for some reason I'm beginning to remember, (but old timers is hitting me pretty hard right now), I'm thinking that the cam freeze plug came out and instead of replacing it, I RTV'd it back into place. 'Cause there's RTV around the cam plug. I just don't vividly remembering doing it. The RTV is the same color as the rest of the RTV I used on the gaskets.
Check for clearance between the cam gear and block. If you can't push it against the block, you may have found what caused the gear to move forward and the chain to rub. That plug should just be a hair in from flush and may be a shallower plug than a frost plug. It isn't there for frost, it's just to fill the came bore hole.
As a second condition to check, see if the cam lobes are centered in the lifter bores. If they are slightly forward too, you know what to do...
