You'd be suprised where oil can get from a leak. I will say that you still could have an oil pan leak at the rear main cap besides the rear main seal. You said that the block was line bored, that can cause issues with the rear main seals ability to seal up I have heard, I never had an issue with my 400 but it was not line bored. Isn't there a shim that gets put behind a rear main seal on a 400 block that have been lined bored, if my memeory is still dependable.

This is not the block that has been line bored and it is also not a 400 block. It is a 71 350. The block that was line bored is also a 350, but it is a 73 block.

This is a stretch but you do have a pcv system on your car? Your not building crankcase pressure and that is where it is blowing out at? Probably not it, but just something to look at.
