Grand Wagoneer with Fuel Injection Hemi?

Hey guys,
I am just curious if anyone has done a Hemi or other fuel injection engine swap on a Grand Wagoneer? I am talking a complete engine swap and not the fuel injection system conversions. I am so frustrated with my 1991 vacuum and carb system that I am entertaining the idea if its not very complicated.
I did I search but I could not find a thread on this topic for the wagoneer.

I try not to refer people to other sites but on www.fsjnetwork.com there are a couple of good engine swap threads. Looks like the GM vortec is a popular swap for both fit and availability of conversion parts.

Basically any engine swap will 'require' a tranmission swap and probably some type of TC as well. I suppose there may be adapters that allow the AMC bell pattern to bolt up to other engines but if you are swapping to a modern engine, you may as well include a newer 4 speed transmission.

Do these engine swaps give the Wagoneer Over Drive?

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.

Thanks for the information! This is beyond my knowledge area, and for now I'm going to keep it that way. It would be great to do a swap to get something closer to 16-18mpg like our old 93 Jeep used to get...with the wind at our back. Or is that possible?

16 to 18 is difficult, even with overdrive. The transimissons behind the 4.0 were not as strong as the th400 or tf727 autos that came with the Wagoneers. They will work but don't plan on big power upgrades to the motor, too much trail abuse or a lot of towing.
