That should be a 4 bolt main 350

quick answer is NO, 2 and 4 bolt main engines both had the same casting numbers. you have to pull the oil pan to be 100% sure.
If your talking about the 400(m) style motor then no it won't. The 400 has the "big block" bolt pattern, you would need a 4 sp from a big block motor to fit.
No it will not. The 6.0L block has been redesigned and the transmission will not even bolt up to the block
