downey offroad has quite a selection of motor/tranny swaps. i believe you can get a kit that has every thing you would need for the exception of the motor/tranny. www.downeyoff-road.com good luck im sure they will have what your looking for.
The V6 transfer case only bolts to the V6 transmission. The V6 transmission only bolts to V6's, so you'd have to change engine/tranny/t-case if you're set on a V6. Leave the stock rear axle alone, it's stronger than you think.Well what would be one of the better engines to put in? Witout having to change the transfer case, i would consider changing the rear end though.
If both are running stock, sure. If the V6 is broken beyond repair, and the 22R is not stock, and you're doing a sfa swap at the same time, then it isn't.Swapping a 3.slo for a 22R is a total waste.
