An engine swap alone will NOT give you overdrive. The overdrive comes from the transmission.
However, it's quite common to also swap the transmission and T-case when doing an engine swap. It makes the swap easier to take everything out of a single donor vehicle.
also, if you're just looking for an overdrive gear, and want to keep your engine, you could swap the transmission. I'm actually looking to put a manual transmission into my wagoneer(will either be an AX15 or NV3550). Sense the AMC 360 and the jeep 4.0L share the same bell housing bolt pattern, just about any transmission that came behind a 4.0 can be mated to the 360 with little effort.
