This winter I would like to do a rear gear swap and OD tranny. My 727 leaks like the titanic and it needs steeper gears (currently 2.71) . I would like to do 3.90 or 4.11 with the OD swap. I haven't found any rh42 or 46 around on Craigslist or Junkyards but plenty of GM200r4 and 700r4 (and 4l60e but the E scares me) I want simplicity. I also want something that can be built and if /when I do a big block swap it can stand the abuse. Plenty of guys making power with the GM trannys I also have a guy around here that will build a Ford Aod with convertor and ultrabell for 3700$ but I dont want to really drop that much coin if I dont have to... They also make the ultrabell for the GM trannys and I found a TCI adapter
TCI Auto 149160 - TCI GM Bellhousing Adapters
plate ... has anyone gone this route with success? What are the benifits or is the ultrabell better ? Is the 42/46rh swap easier and can they be built on the cheap and still be able to swap to big block bellhousing in the future? Lotsa plans and a slim wallet.
