I'm at the end of my rope!

BACK STORY: I bought this motor with a spun rod bearing over the winter and full rebuilt the engine with forged internals. When I put it in the car, on the first crank, I found it pouring oil out of the bell housing. When I took it apart, I couldn't figure out where it was coming from. So I resealed the pan (used permeates black RTV) and tried again. It leaked the same. I pulled the trans and replaced the trans input shaft on the chance that it was bad. No change. I then replaced the rear main seal for the second time and resealed the housing around it, no change. So I did some research and found that my arp main studs cause this problem and I needed to cut them down. So I did and it looked like it fit perfect resealed it and it still leaked.

Short story: it leaks out the bell housing.
Resealed oil pan 3 times= still leaking
Resealed main seal housing= still leaking
New trans input shaft seal= still leaking
Grind down ARP main studs= still leaking

WHAT AM I MISSING?!?! Of course all I can do is look at the leak from the little key hole at the bell housing and see the leak. I'm pretty sure it's coming from the oil pan from what I can tell.
