this is just a toy, no street time at all. I just don't want to invest a lot in the toyota axles, mostly because I have the 1-tons setting in the shop. My main concern is just the drivablity of the truck off-road. All I have had were K-5s with 1-tons and big blocks, but I want something more capable in the rocks. I have been considering a 4.3 with a SM465 and 208 to get a decent crawl ratio, but I don't want to spend the money if the 22r and dual cases will work.
