Now that I am finally getting around through my divorce, I am going to get back on my buggy that I haven't touched in years. Money is still a bit tight so swapping the motor isn't an option at the moment, but something that I would like to keep in mind for the future. Don't really plan for a large V8, but a built ecotech or something down the road with a few hundred horse power at most. Currently have a 2.5L backed by manual AX-5 and doubler 231/300 that I am surprised lasted as long as it did before tear down. I have been wanting to swap to an auto and I came across a rebuilt manual valve body 904 for $700. Seems like a good deal, but I don't know much about the 904's. I will probably ditch the doubler and go for an Atlas if I go this route. I am not extremely experienced with Auto's so I guess my question is if this is a good route to go? Axles are 1 tons with 5:13's and running 40" or 42" tires, so what ratio would be ideal on the Atlas also?
