I do beleive you have to check the bell houseing bolts to see if they line up other then that i think the only other thing is changing the injector plugs. lol i have to run out to my dads truck and see what he changed. He did that motor swap from a 2.8 to a 4.3 crate motor.

ha you have the same motor as my 86 jeep. man I hate that motor. I asked everyone if I could put a 4.0 inline 6 but they said it would be to difucult. Does your 2.8 have all the CA air restrictions crap on it?

have you ever thought about using a crate gm 3.4 instead, should be an easier conversion than the 4.3 with similar power gains, and over the 2.8 it will be a night and day differance.
