no its a 4 bolt main however it has 2 of teh bolts on the side. if you look at the main caps it has 2 bolts with 2 locating pins. and yes there are superchargers for it, i think kenne bell has one.
a built 32v 5.4 would be bad ass and if it had a blower it should make a lot of hp. If you put that motor in an old fox body lx trunk style it would scream.
