Beauty of chevy a 4.6 and a 9.3 will fit in the same mounts just about.

simply put no its not that hard if you have a complete motor to drop in.

"common" issues will be radiator Exhaust front springs.

really depends on how stout of a engine you are throwing in, but everything from the back of your crankshaft to your wheel studs could also factor in.

for those who are guessinga 9.3 is a 572. whats a 10.3?
