Considering an OM617 into a 1982 4x4 pickup. I've seen swaps with later trucks but can't find a thread with a 1st gen. I've heard there are clearance issues and want to know if that's true or can be overcome. Also other than the "cool factor" of the rattling motor, how's the power compared to a 22R? I'm not interested in performance but don't want to go backwards for a lot of time and $$$.
