If I was building a truck I would want to 727, if I was building a car I would want a 904... They're both pretty close to the same internally and both share the same valve body. 727 has bigger parts but generally a 904 can be upgraded pretty easily..
I'm in my mid-50s and still feel far too young to have to rely on an automatic, but when the time comes it will be at 904...
Good to know and i lile your input, i would go woth a 4 speed but feel lile the cost and amount of work would be a lot. I would have to have a 4 speed but money getting tight as most was dumped into engine amd and suspension upgrades
