I have no clue how much the T56 cost or what I will need even. I am not that smart. I will ask Casey (motor builder) and the shop thats installing but your input here is always good and welcomed. its a automatic and a street car, want to keep it that way lol
what the best cost effective or just best way for me to do this in your opinions please. will I need a new 3rd member also? I have new 3.77 gears, posi and Moser axles. so I am thinking trans and 3rd?

62 impala if that matters
ha well see how smart I am T56 only in manual shifting.

what about the 4L85E that holds 700TQ would this be a good choice for me? at $3000 I can sell my 6L80 and be no where near the $5000 to upgrade the 6L80?
