I need to get a life. Sunday afternoon and I just spent over two hours reading all the posts catching up from post #1 to #922.

Here are the things that are probably involved:
1. Distributor driveshaft wear from touching sides of block hole
2. Destroyed bottom distributor bushing
3. Enough vibration to shake the oil pickup loose

So none of the three usually happen very often and not all together. MSD has produced thousands of distributors with the funky bushing probably without a wear problem, oil pump driveshafts normally have plenty of clearance, and if an oil pump does come off it is after considerable time and not fresh off the dyno. So something isn't right and caused these problems soon after the build. Noise down at low RPM turning into a vibration at higher RPM's which would be difficult to catch.

I also see photos of the copper coating on the cam so it's probably a Crane cam. This also means that it is probably a cam with the cast iron end pressed on so a standard distributor gear can be run.

I'd be looking at the cam...
