I like the chevy 350 idea, even thou I'm a Ford guy. Theres no arguing the point that there is about a zillion 350 chevys and trannys to go with them, and the world is awash in parts for them,oem and aftermarket, usually cheaper than the other 2 of the big three companys parts. I've seen guys rebuild turbo 350 auto trannys on a tarp out in the back yard and they ran like new.Get an older Blazer or a newer one and swap in a no electronics engine, and a non-overdrive tranny, they are MUCH easier to rebuild. You can stock up on spare parts cheap. Same line of thinking as me taking my AR instead of an AK---parts availability.
