Is a 85 Dodge 318 short block w/heads compatible with a 94 Jeep 318 motor?
I have a 1994 Jeep Grand Cherokee that needs a new 5.2L motor. I have found a 5.2L short block with heads that is out of an 85 Dodge. Will the 85 5.2L and heads work in my 1994 Jeep?

No it will not unless you feel like doing a lot of work. The 5.2 in the jeep is a magnum motor. THe 5.2 out of the 85 dodge is a LA motor, pre-magnum. The heads are designed differently, the intakes are completely different, the oil gallies from the block to the heads are different (so you can not just swap out the blocks or the whole top end), The exhaust ports are different, etc. You need to find a magnum motor (92 and newer). The small block motors that are 91 and earlier are all LA motors. You should be able to find a magnum 5.2 used and complete for a few hundred bucks. Any out of a 94-01 ram truck, 93-98 jeep grand cherokee, 97-01 dakota, 97(?)-01 durango will work.
