Just to give everyone an update. I jumped the gun and already bought a motor today. Its a 1986 302 out of a mustang with 75k miles. Its not the exact year I wanted but since its a speed density motor and has a little less power than some of the other foxbody motors, but I figure I can convert to mass air if I want to in the future. I got to hear it run and got it for only $375 with headers, all accessories, computer, harness, etc. Not sure the headers will fit in the jeep but I figure I can sell them for something to get some money back if they don't. I'm pretty excited I can finally start gathering parts! I have a wait 2 weeks to get it though because its still in the car and thats when the guy can get around to pulling it but thats okay with me since I'm not in a hurry with this.

I'm glad I am going the ford route. I actually had an 1986 mustang gt that had 245 rwhp and I loved it. I still regret selling that car . Hopefully putting a 302 in my YJ wil bring back some good memories in the mustang

Nice, I had a 92' LX. Only had the 4 cylinder but I liked it. I had my 03' GT until I traded it for my Jeep. I would eventually like to go with a 302 or maybe 351 in my YJ.

Anyone know where I can get the wiring diagram for the the 86 mustang 302 I'm getting? The computer in the car had a 'VJ1' code on it which according to this page (http://oldfuelinjection.com/?p=17) is the correct year computer for the speed density motor.

Remember that year had those oddball heads if you change heads you might have valve clearance issues with the pistons.

Can anyone tell me what year bell housing can I use to mate up the 302 to my ax15? I plan to use either the AA or Novak adapter but all I can find that is a for sure fit is a bell housing form a 1987 or 1988 f150. Shouldn't an 84-88 work? what about any of the newer ones up to 1996? I remember reading that ford changed to a different trans in 89 but I'm curious to see what other years I could be looking for.

Good choice on the 302, small, light, good bottom end. I stayed speed density for the simplicity on the trail. I used an 84 f250 bell housing with a novak 3/4" slave to match the jeep master. I am running the np435 out of the same truck so I'm not sure if that's the one you need for the ax15. Make sure the headers and motor mounts work with each other before committing to either.

Might need to call AA or Novak, I would think they know what to use.
Here is a couple links that I found might be useful.

I went to the junkyard and asked for a 81-91 ford truck (per Novak's web site), smallblock. They came back with one from 89 F150 with the clutch fork, dust boot and the slave bracket bolted the bellhousing. Try to get the additional parts when getting your bellhousing, save a lot of furstration hunting for the small stuff. Note this bellhousing fits the T18/19 and NP435 transmissions. Not sure how/if it adapts to AX15.

Fixed it for you.

OP, be sure to start a build thread when you start tearing the Jeep down. It helped me quite a bit.

If you don't mind me asking, how much did it cost for that? I thought I heard they changes the trans on ford trucks in 89 and it wouldn't work. Maybe that was just for the trans adaptor from AA. Either way, I think I will be giving them and Novak a call to get more details

I did not pull it myself so it cost $125, and included those additional parts whcih I specfically requested. I do not know when they started using 5-speeds in full size ford trucks. I do know that if you plan to use an external hydraulic slave it must be the bellhousing that has the bracket (attachement points) for it. The late model mustangs bellhousings I saw did not have the provisions for the external slave and bracket. Mine is from a 4-speed truck and has the "buterfly" bolt patten for the trans.

Note I have seen bellhousings locally from private sellers for as low as $40 but none had the additional parts. I accepted the additional cost to get a complete setup. Not sure how hard it would be to find that slave bracket or clutch fork. Its the small parts of a larger assembly that can often slow-roll a project.
