Installing a stage 5 trick kit with VS8375 on bone stock (reg cab, short bed 2wd, 111k miles) with 4l60e/3.23's/street tires.

I have to get it rolling under its own power while finishing new drive-line. No digs, just cruising/rolling into boost.

Which of my 3 tranny combos should I use for now?

1) Run the stock 4l60 while limiting boost. (Keep TM on, big cooler already installed)

2) Install my fresh TH400 and :

A) Used TCI Streetfighter 3600 stall from e85 BBC Foxbody build?
-or-
B) Fresh GM unit that gave about 2400rpm stall in a warm 454SS build?

Thanks.
