I got stock mounts in mine, plenty of room on the right, had to butcher the left side to clear the header tubes. Did get it in place though. Might try swapping sides of the mount, motor side. I do know the big block ones are like 2-1/8 inches deep/tall, small block ones are shorter.
Working with the seller, we'll see. He was reluctant to sell it to me because "it's a four bolt main"...
