Just picked up an 86 today.

Well guys, the jeep fever got to me again. I found a good project 86 cj7 today. It has no motor, trans, transfer case, top, and doors. However it is very solid, minimul rust, and almost perfectly straight. My plan is to do a frame off and go through it all. I had an 84 for a daily driver for quite a few years and then sold it off. I always wanted to do a restore on it, but kinda hard with a daily driver. Now this is my toy, and I have plenty of time to tinker with it. So the first things first. I need to figure out what motor to put in it. I am a Ford guy so it will be either a Ford or a 4bt cummins. My last one I did the 5.0 efi in it. I loved that thing, lots of power and got over 20 mpg down the road. So I may do that again, but had anybody put a 5.4 in one yet. I am kinda thinking of that too. What do you guys think. I want to figure out a motor before I rip it all apart. I want to get one mocked up before I get around to body work and pain.

Sounds like a good project candidate. BUT NO PHOTOS AND IT DID NOT HAPPEN!!!!

I have no experience with those engines but Novak transmissions has a good technical page on common swaps and issues with each one.

Here it is. I think it will be a fun project. I am really looking heavily into the 4.6/5.4 motors. Right now I am trying to figure out what modular motor would be a good candidate, and what would not. If not a mod motor, then I think I will go back to a 5.0 fi sbf. I have heard to manny horror stories of the 4bt motors being extremely vibratory and loud. I can believe that because I actually have a 4bt motor in a chipper I have. It rattle everything apart on it.


If any of you know of good info on the modular motors, it would be greatly appreciated.

it looks sweet, a blank canvas, what are you trying to achieve in the final build? Is this to be a street machine, a trail rig, a rock crawler, a mud slinger?

Uh its going to be more of a stock jeep with a EFI motor in it. More of a street jeep with a small lift than anything. Yes it will see a few trails here and there, hunting and what not, but that about it. Really it will probably be run around rig. I am tired of running around in my full size truck, and I always get in trouble when I steal my wife's expedition.
The expedition is the main reason why I want a modular motor, I love that 5.4 in my wife's car. Lots of power, quiet, silky smooth idle, and starts every time.

nice looking jeep for sure! my vote goes to the 1999 and newer 4.6, 4v, dohc engine. lots of them out there, more than enough hp and tq for "running around", and a nice broad power band.

1966 CJ5A, mods are coming
1966 Wagoneer, bone stock

I vote for 4.6 supercharged DOHC 4v out of '03-'04 Cobra. Then the Jeep can do wheelies

'85 CJ-7 Laredo currently under construction.

Forget the Jeep! Bring on the Mustang!!! Could we see more of it?
My first car was a 65 Mustang 4 speed with a 289. It was my first restore also. That was 35 years ago. Then CJ and 76' Bronco. I always dreamed of the bringing back a Jeep and now since I have it I want a Mustang. Just not enough room for so many toys.

Okay, back to your Jeep. You should guess my choice, since my love of mutangs,is a 302. Combines the stang motor in a Jeep.

Here are a couple pictures of that mustang. 66, 332 stroker motor, solid roller cam, victor jr intake, afr heads, 750 mighty demon carb, 5 speed trans, 9" rear with Detroit locker, Bought it when I was 14, spent every penny I could earn on it. Was able to get it on the road shortly after 16th birthday, and was my daily driver for about 2 years. Sits in the garage 300 days of the year now. Took it to the strip couple years ago, got a 12.7 with street tires. It will run mid to high 11's with some tuning and slicks. Currently fuel line from tank is too small and it runs out of fuel in 3rd and 5th gear, making tuning a bit difficult.


Here is also my old jeep I use to have. You can see there the 5.0 i had in it. Kinda rough looking, but I did that in my drive way while i was away at college.

So there you go, now you can kinda see why I want to go 4.6 or 5.4. I want to take my time, and enjoy a new challenge.

You should look up Coiz's build thread. Lots of info, and I think he talked about the mod motors in there.

I do know the mods are a lot wider than the SBF engine, that may be an issue unless you don't mind removing inner fenders and fabbing headers.

Well I am starting to lean more towards the 5.0 again. I have been trying to find out swap info for the 4.6 and 5.4, but there really is not a lot out there. I also measured my 5.4 in my expedition and It will be very hard to fit one in the jeep. I think the motor will fit with a little fab work on the inner fenders, I would have to do custom headers I think, and height would be very close. However the main problem is the steering shaft would be right in the way. I am not sure how to get around that other than doing a complete custom steering shaft that snakes around under the motor or something. I have been trying to get my hands on a junk 4.6 or 5.4 to mock it up and see if it will work, but I have not been able to find any complete motors. Then there is also the tranny the problem. I would most likely have to run a automatic tranny with the modular motor because there are very few manual transmissions in newer rigs.

So all in all, i have done nothing to the jeep other than research.

My unsolicited choice would be a crate 351. Maybe a stroker, w/the injection like you had before. I'm thinking more low/mid range power because of more stroke than bore, as the 302 has.

. 360 HP/400ft lbs for $4300 sounds like a nice CJ combo. I just googled this up as an example of what I had in mind.
BTW, you didn't luck out and get an '86 w/a D44 rear? I'm doing a frame up....'cuz I needed a frame. I found a late '86 w/a D44.
DARN.....WRONG pic, was trying for the rear shot!
