Re: 350 or 360 which one is best for me
It depends on your aspirations for the jeep. The T5 is often referred to as being questionable behind a healthy v-8 (not to start a tranny comparo war or anything). If you're potentially interested in swapping trannies and going to something stronger, you'd probably have an easier time finding a 350 and a compatible tranny/t-case than you would finding the AMC equivalent or adapters to make something else work. If you're happy with the tranny (or think you have a line on an AMC tranny or an adapter), then go with the 360, it'll be less expensive, easier, and more authentic (had to say it) to swap in.
