46 CJ2A engine swap

I have a 46 CJ2A with the original engine. Problem is, it has a crack in the block. I also have a 93 mercury engine, it is the 3.8 ltr V6. I would like to put it in my Jeep. I would get rid of the fuel injectors and all electrical and put on a coil and regular distributor and also a carb.

Can this be done? Are there parts that will allow this engine to connect to the original bell housing?

I'm not sure that you're going to be able to find an adapter for that Ford V6. Novak-adapt.com has adapters for the Ford I4 OHC motors and the Ford Windsor V8s. You have the T90, which is a great transmission and will hold up under even V8 power. If you asked me, I would try and find a GM Iron Duke or a Vortec 4.3L V6 and swap that in with the GM adapter for the T90.

the ford 3.8 shares its bell patern with the ford small V-8 (windsor) engines so adapting shouldn't be a problem. question is can you get intake and carb to fit it? also you want to be sure the 3.8 was out of a rear wheel drive car if not, the mounts will present a problem and the fwd 3.8 was JUNK (IMO of course but I have had both)

Are you saying Mercury as in the car (junk), or Mercury as in OMC/Mercruiser? The OMC swap would be GM, not Furd.

I was saying the ford 3.8 in the taurus/sable platform was a weak engine. in cougar/t-bird/ltd platforms they were better/ more dependable and much less prone to head failure.

edit: oops read your post wrong Jayhawk ... and that is a good question when I read it I automatically assumed car.

I would keep that fuel injection if at all possible. It makes for a much more enjoyable jeep.
