Well, I ended up using the back 2 main cap bolts to clear the windage tray and
oil pan. I have a new problem. When I was installing the
oil pump drive shaft, I realized the Tenneman clip did not hold the shaft in the block. The hole in the block is larger than the ring. With a brown and sharpe caliper the ring outside diameter measures .510". It will fall through the hole in the block. Is my block shot or what? The distributor shaft is supposed to be snug in this hole (my understanding). I didn't have the distributor for testing but the shaft on the distributor is much less than .500". My friend told me the hole in the block should be ~7/16". Please tell me I am missing something here. WHY WOULD ANYONE DRILL THIS BIGGER? Keith Craft, are you out there? Ever seen such a thing?
