What would the cost diff be between the 4l80 and the AODE (? don't speak Ford).
My understanding is the Henry trans has a reputation that isn't the best, so would it take more to build to a similar level?

I would like to apologize to LJS30 for my part in taking your thread way beyond your original question. There is some good info flowing through here.

I will be hanging out with my transmission buddy the end of the week and will ask him to give me a guess on both of them. The one thing my buddy will ask is how much power are you looking at? In both cases, with a good rebuild and minimal hard parts they will be able to go behind a pretty healthy motor.....In the 80's case, with just a few parts tossed at 1200 hp is not beyond reach...
