Ever since I decided I was going to buy a fsj, the one thing that I didn't like about them was the lack of fuel injection. I figured this could be corrected with a tbi system of some type. Only problem is that the 360 currently in the G-wag needs a little attention. Every time I drive it the warm idle pressure seems to be lower and lower. I'm probably around 5 psi at this point. This fact combined with the leaking front seal, lifter tick and the need for a valve job leads me to the conclusion that while a tbi system would improve driveability, it does not address the problems that the motor currently has.
Which leads me to the point of this post. I've found a 95 ZJ with a 318 that I am thinking I could drop the engine/tranny into the G-wag. It's (relatively) low miles and is a cheap option due to a roll-over.
now time for some discombobulated thoughts:
While the 318 is smaller, I think the more modern design with the mpi would make up for the loss of cubes.
The overdrive gear would be pointless with my 3.31 gears and 31" tires now, but would be excellent after I change the gearing.
From searching this site and others, my NP229 should bolt up to the A518 (both being 23 spline) please correct me if this is wrong
BJ's has motor mounts for Mopar LA series engines, but IIRC the magnum engines mount differently.
While my mpg would not increase substantially, I am mostly after better cold starts and driveability at various altitudes (live at sea level, travel to 10k ft every year)
the 95 is pre-obd2 and would be easier to wire into the G-wag than a 96+ engine
the 318/A518 is longer than the 360/727 so drive shafts must be dealt with
</discombobulation>
I've searched for other people who have done this and haven't found any completed projects. Most go for chebys of some sort. I am I mopar guy and would like to work with what I am comfortable with.
I don't want this to come off like I don't like AMC engines. I have no qualms with their performance only that it is 60's technology and upgrades are more expensive than other brands.
Feel free to flame away and try to talk me out of it, or offer advise and encouragement. Thanks

, engine must be an 87+ in order to go into my rig. A 440 would be pretty sweet in a trail-only rig though
