Whad\'ya think about the 700r4? Being new to the K5 world, I'm already putting together a wish list. I bought an '86 from a dealer (I had a dodge that NO ONE wanted to buy, so had to trade it in), and for the most part, the Blazer runs/drives great. But I'm sure in due time, the 305 will have to be swapped and the tranny rebuilt/replaced. I've heard a lot of people talk about the 700r4's and am wondering what the general consensus is. Some people seem to love them, some people seem to hate them, but then are also unhappy if they've swapped in a th350 in the 700's place. Also, for those who've put in new/rebuilt trannys, can anyone recomend any good sites/stores with quality units and decent prices? All feedback welcomed.
