That's going to be a cool engine for that Sammy. How are you going to route the exhaust? The frame rails are a little narrow to use stock manifolds. Are you going to raise up the engine above the frame or do a front subframe to clear the exhaust?
Oh, and good call on the 700R4. Great transmssion as long as you don't go with an early model before GM upgraded them.
The question is though, what t-case are you going to use and how are you going to squeeze that into the short wheelbase of your Sammy?
As far as getting my exhaust and rear bumper on, that's going to happen tomorrow. Over the next week and next weekend, I'll be doing the necessary fixes on my Cherokee to get it running. Then a 4" spring lift to clear the tires since they rub a little as it sits now:
