Ford 4.0 swap for my CJ?

Well, I am able to get the CJ project going again, but on a smaller scale. I am looking to make my '74 CJ-5 a capable desert jeep without dropping big dollars.

I want to add power steering, power brakes, air conditioning and fuel injection. I think I would like to keep the axles (Dana 30/44).

I know prevailing wisdom here is to go with a 5.0 V-8, but then I have to beef up everything else. I have a line on a 97 F-150 with a 4.0 V-6 and 4WD. I am thinking that the V-6 might be a decent way to go, since I won't be a hard core rock crawler, the horsepower won't be too much of an issue.

I have an NP435 that I want to put in the CJ, I think that the V-6 will bolt up to that, but the F-150 has a 5 speed in it (a ZF?).

So my questions:
What are folks thought on the Ford 4.0 V-6?
Can I use the Ford short block motor mounts?
Is that tranny a ZF and would that work in a CJ?
Has anyone done this, or would it be just as easy to go with the 5.0?

Don't know about the 4.0L. If you use a stock 5.0HO, your're only getting 215 HP. I don't think you need that much beefing up unless you plan on a lot of wide open throttle action.

The Ford 4.0 V6 is a great engine - good torque, power. Ford had problems with the gaskets leaking on the early 4.0L but they have seemed to correct that.

If the tranny is a ZF (it probally is), run........don't walk away from it. They are a very weak design. I can sell good ones wayyyyyyyyyyyyyyy faster than I ever get them. Stick with your 435.
