I have an 89 YJ with the 258. It's dying a slow death. I have a buddy with both a 304 and a 360 for sale. Has anyone attempted to plop a 304 or 360 in a YJ?

This is an 85% offroad only jeep (can't say no to those woderful summer joyrides :) I have the AX-15 trany with the NP231 trans case. I really want to keep the same tranny for now as I'll be getting an better one in the late fall and I need to roll this summer.

What should I expect? Will both couple to the Ax-15? Do I need to change flywheel? ...

Any help, experience in this swap, heads up would be appreciated.

Try the Search feature... it works.

Thanks. Saw that someone was doing the same swap but his email doesn't work:nuke:. I need speifics like can I use the stock 258 clutch/flywheel/pressure plate... (it's new...). What possible trouble should I find with mounting it to an AX-15. Also, what kinda carb would be the best match for the 360?

<taking a deep breath... and now a big sigh?>

No, you can't use your old flywheel. AMC engines are externally balanced.

Your AX15 should bolt up.

Clutch disk will be the same... may need a new cover.

The 2100 carb that is on the 360 is an awesome carb. Don't put a Holley on there.















Dealing with 2 kids under 4 really improves one's patience.

I have been considering this too. I have a couple of things to add.


Will the ax-15 throwout bearing setup work with the 304 pressure plate?

Are the motor mounts the same (bolt in/304 or 258) or do you need to make new ones?

Thanks.
