Default TH350/TH400/or Powerglide

TH400 vs Powerglide

This is going in my 05 GTO that is a heavy pig and coupled with me weighing 270 it's almost a land whale. I don't plan on stripping it down either. I want to be in the 1000whp crew within a year or so. I'm trying to sell my 6-speed right now and hopefully buy an auto soon. It's not driven on the highway much and I have no problem driving 65mph if I have to. I would want to get a lockup converter as well. For now I'm just going to go forged stock cubes and hit it with a 200-300 shot of nitrous. Once I blow that up hopefully I'll have enough saved for a stroker. I'll also be using 26" slicks.

-Which one?

-Which ratio's?

-Who sells em?

-Stall rpm?

Edit:

From reading on here I guess the TH350 is out.

I believe with me in it the car is close to 4000lbs.

Cam is a 242/248 .621/.615 on a 111 lobe sep.

The 400 was not offered with lock up. The Glide was not offered with lock up. That leaves the 350.

If you would like to discuss a build, give me a call and we can kick it around.

I'm awaiting payment for my t56, so I'll be able to buy a custom TH400 with a lockup 4000 stall from a guy I know.
Now I just have to save up for the new shifter, driveshaft, and speed sensor.
