I would suggest the 4L80E. Yes the controller and a TPS add up to some money. But you could get away with running a good used 4L80E versus spending $$$$$ having a 700R4 built to hopefully hold up behind a big block. The other issue with an electronic trans is the speedo is electric also. There is no speedo cable connection. There is info online on how to wire a factory ECM to operate an electronic trans as a standalone. That could be an option if you have more time than money
