Engine Mounts

[Allen9878]

I have a 1980 CJ5 with a AMC 258 i6 / 4.2l I6. I will be putting in it a 4.0L from I believe a 90 wrangler. I have never done a switch like this and was wondering if I could get some help with what engine mounts I would need to mount a 4.0 wrangler engine to a CJ5 frame? Maybe its the same but I doubt it.

Also I am putting it in with a ax15 Transmission mounted to my Dana 300 . There will be some clearance issues with the bell housing and the front drive shaft. How do I go about getting engine mounts that offset the engine to the drivers side about an inch?

This might be a very easy thing to do, but like I said, I am new to this so if I can get some input to what regular engine mounts I would need and how I go about finding the right offset ones I would be very greatful!

Thanks!

Any Thoughts On this?

The AMC 258 i6 / 4.2l and the 4.0L should use the same mounts. They are basically the same engine block.
As for off-setting the engine, you will need to have the engine mounts custom welded. I'm not sure that should be necessary. It is true the CJ always had the front drive shaft on the right and the YJ had it on the left. But I don't see why it wouldn't work keeping everything down the center. Maybe slight grinding on the bell housing might help. But if you move the engine one inch to the left it will not move the drive shaft one inch away from the bell-housing. Are you planning on leaving the TCase in the middle? That would angle everything. Since the bellhousing is half way from the front of the engine to the TCase then you would have to move the front of the engine 2 inches to move the bell-housing one inch. I don't see why any of that would be necessary.
