This one's an OM617 on an '86-'89 body style with IFS. Even though the truck has a bracket lift, it looks like the oil pan clears the steering linkage. The front diff normally sits just under an inch higher and back further where it looks like the pan curves up anyway - it might be close, but it looks do-able without having to make much clearance.
...... i love seeing trucks I've worked on, on the boards ......
that motor setup is amazing, the conversion was done at defiant 4wd
using a custom adapter plate and pilot bearing adapter on a re-drilled 22re flywheel, there is a lot of space issues on the trucks (we've built 2 ome617 trucks) but for the power and economy gains it was worth the shoe-horning it in. I drove the first one we did and the power was amazing it had no problem pushing the 38" tsl's
so my vote would be for an ome617 ..... but i wanna keep my tranny ...yay ...new adapter plate ?
