4.8/5.3same block and heads

5.3/5.7/6.0 same crank and rods

4.8/5.3/5.7/6.0/6.2/7.0 are all the same size externally, all interchangable

Nope, that's why you see the guys going to 370 and 408 swaps always start with a 6.0 block. The 5.3L can only be bored to a 382 ci engine without serious money.
