Sorry, I should clarify. It's a D.U.I. (Davis Unified Ignition). Basically a HEI Distributor with the coil mounted on top. Haven't got it on yet but I have read alot of good reviews about it.

Here's my 86 CJ 7. Looking at doing an engine swap, just searching for the right engine. I think I found a 5.3l with everything I need for a decent price. Then it'll be lockers, 37" tires, and who knows what else.

Depends on intended usage i guess. I pulled the 3 speed out of mine and am using a th400/dana 20 from a j truck. Ive built mine for 95% trail use and prefer the auto on the trail. If i were running say. 50/50 street and trail id try to find a t176 or t177 4 speed because of the decent first gear and i prefer the manual out on the road. For mainly road use id probably swap in an ax15 to take advantage of the overdrive. A t5 was offered as a factory transmission, and has overdrive but can be on the weak sideAny opinions on manual vs automatic for CJ7? Beyond preference, is one better than the other in these old Jeeps?
