Re: shortest engine/autotranny/TC combo for 1969 DJ
Your on the right track in staying with a v-6, since they are as short as a 4 Cyl and of course give more power... as far as auto trannies, I think I researched this once and the th350 is about the shortest you can get, or at least it's within like less than an inch longer than the next shorter....but it is the obvious choice to bolt to a 4.3(chevy bellhousing) or buick v6(bop bellhousing). Dana 18 is the shortest transfer I've ever seen, but you will need an adapter, and the question is how long is the adpater(how much length will it add)and how much will it cost? It has an added benefit of a lower rear output to help your driveshaft angle ( your rear shaft will be SHORT so every little bit will help) and it can accept a warn/saturn overdrive that the th350 doesn't have. A drawback will be you need to get an offset 44. If you go that route look for a later offset 44, (like a 70-71 I think) they used flanged, 30 spline axle shafts as opposed the the earlier 19 spline 2 piece shafts ( yes, just like the dreaded stock amc 20 shafts). The offset rear has an advantage in the rocks as you only have to miss that rock with the front axle and the rear automatically misses to! Oh yeah, with the dana 18 you automaticallt get twin sticks to!
