Gonna build a Jeep

[84ZMike]

Bob,
Great find......I'll second the atf as it has cleaning agents....plus it's a lot cheaper than kroil.......I'v used a mixture of atf and diesel to thin it out some so it will get down the cylinder walls........as well as removing all the plugs when trying to turn it over by hand....well more like rocking it as you don't want a ring to break or scrape a large amount of rust at one time as it can damage the cylinder walls.

Hey guys, I think you over looked one minor detail in giving advice on freeing up the motor, that being WHY???
If aametalmaster has got a 302 ready and willing, that ole 6 banger is nothing more than a boat anchor to me. Forget about wasting the time on a tired old beat down motor when you got the fun and challenge of fitting the Jeep with the 302. Besides you don't need a welder to rebuild a motor, but you do need one to fab up the new mounts and towers. Get to cutting and welding and forget about these other suggestions, go wild and create a monster while you're at it. Dave

i was thinking along the same lines as you . he said he tryed it out and its toast, he has a ready to go one in the basement. why waist the time on the dead dog. its not a clasic resoration project where it needs to stay origenal. its going to be a play toy, so why not make it a better toy wile you are at it.
not a big fan of the ford's but the 302 is an exelent motor as i understand it so go for it. start fabing up some parts and get at it. take the dead one to a scrap yard for scrap steel and use the $$ to buy some beer for the project.

Im guessing the '96 is a typo. If it is an '86 CJ-7, the last year they made them, then you should have the more desireable Dana 44 rear axle instead of the AMC 20. Good find for $300. Lets see some pictures.

1976 was the first year that AMC went with the 20 rearend. They had a lot of problems with the two piece axle-it always wanted to revert back to two pieces in high torque situations. A few companies made a lot of money supplying aftermarket axles that work on the 20. what year did they go back to the 44?

the straight 6cyl is good for general off-roading. A v-8 in a cj is good for burning rubber, trashing transmissions, stripping those amc 20 axles, and creating controllabilty issues because of way too much hp in such a light duty, short wheel-base, high cg vehicle. Gave Ralph Nadar a lot of ammo.

if i ever decide to play around with an engine swap i figure i will use a gm 4.3 v6, same bore/stroke as the 258 but in a v package.

Not to hijack your thread but i just welded in a Vortec V6 in a Geo Tracker, what a screamer and rubber burner. We also just made it 2wd. Will get some pics tonight...Bob

Yup. Im well aware of the model 20 problems. The HD versions of the AMC 20 used in some of the wagonners had one piece axle shafts and held up much better than the CJ versions. The first axle swap on my '98 TJ was a HD AMC 20 rear, Dana 44 front out of a waggy.. they held up very well considering what I put them through. Bent one rear axle shaft and broke a few front stock axle shafts and joints. Im running a Dana 70 rear and Ford RC60 front now

The only year they used the 44 rear in the CJ's was 1986... and IIRC there were actually a few early 86 CJ's with the AMC 20 in there. Most have the 44 though.

I would like to know what I would be gettin into because I am going to eventually tear into the same model jeep because thats the one my mom had way back when and she said thats the one she would like to have rebuilt so I of course said shure when can I start. I am still lookin around to find a good deal on one locally wish I could find something as nice as what you did
