Stay away from the Toyota 3.0 gutless wonder. Ask anyone who has one or had one, and they will tell you that it's a dog. Gearing is good, but for highway and hauling, it's not werth the swap. Check the website I left above, thats the choice if you stay with Toyota. I hear about the 7M swap, has any body talked to someone who did it? How did it work out? I'd like to know. Not sure that one is worth it eather.
