AMC 360 engine conversion
Post by jeepcjjones on Oct 18, 2006, 7:22pm

hello all,
I have been a long time and multiple jeep owner but just recently have obtained a m715. The stock engine drained about 3 gallons of water and no oil from the pan. I would like to swap and AMC 360 from a rusted out chief. I have search the board and found that the swap is basic except for the transmission input shaft needing to be modified. I am not sure what exactly is needed. Any information on this swap would be appreciated.

Thanks

Does your donor Jeep come with a manual trans? If so I would keep in and install with the engine. I'm sure someone here has done a 360 swap. I am doing a buick 350 swap, not quite finished yet.

The donor jeep has a t18 transmission with a Dana 20 transfer case. I probably could swap the transmission as well but was thinking it may be better some other projects. was hoping keeping the old one was fairly simple.

Not sure what you would need to do to adapt a 360 to a factory t-98. I used a t-18 input shaft onto my t-98 with a different bearing setup to adapt a buick 350 to the t-98. I believe the t-18 bolt pattern is the same as our t-98, but not positive. The 360 bellhousing would work if the bolt patterns are the same.. You would have to make sure the input shafts were the same, and get a pilot bushing that works. Then of course all the proper clutch pieces. I'm sure it can be done, just don't know the specifics. I wouldn't run the dana 20 transfer case personally, but the t-18 trans should be up to par. Although both came in fullsize Jeep trucks. I think the M-715 is probably heavier than a civilian Jeep truck, but then again I've never weighed either. Good Luck

the input shaft on the J-10 is longer I believe by 1.5" or so. I looked at doing that and decided to go with the Chevy and Novak kit.

Doing it again, I would use the chevy motor and tranny or use the Jeep motor and it's associated tranny. Then all you have to do is the mid-shaft or tranny mounts.

I would use all the stuff from the donner jeep the 360, the t18 and the d20 it will make your life much easer and will hold up well

Use the 360, the t-18 with a yoke and go with a 205 or 202 divorced case instead of a 20.

Id recommend the same thing as fisherman. However, if you want to keep the stock trans and tcase, i believe that the t18 input shaft can be swapped into the t98.

Yes it can, I have my factory t-98 with a longer input shaft from a t-18 to bolt everything up to the buick 350. Just needs a different style bearing, carrier bearing and input shaft from the t-18 and it will bolt to your 360, I do believe.

Any ideas on where to get just the input shaft from a t18. I have found a 360 engine without dismantling my Chief so I really only need the input shaft. Thanks

Scrounging around, craigslist, tranny shops, Jeep junkyards. If you strike out I'll bet I could come up with one, do you have the manual trans bellhousing also?
