On a side note, I see that 4L60e not lasting very long. So I throw out there the thought of not spending big $$$ on a good converter to only contaminate it when you puke the trans.
Regardless if who make the trans.

Its a performabuilt trans and It will handle this setup pretty well IMO. It did last year, the only thing now is the spray is a bigger shot and a new rearend. ALso I know I need a antiballoon converter and 4k tops.

damn that sounds like a really stout setup. i'm wanting to do something similar to that but i have a th-400 ready to drop in. I think i'm headed with a higher stall though, more like 4500+ but it's a drag car only. I'd think a 4k stall would be awesome for you.

Depending on the Passes, Power, and if Applicable Street Miles, these transmissions need matience.
Even TH-400's or Powerglides, or hell even Valve Springs have matience intervals. Just a FYI incase you blow the load on a 'verter from Circle D or Yank.
I would be PMing them.

3000 stall for a 4l60. 3600 might be too much and inefficient. I had a 3500 loosened to 4000 and the rpm's went up 1000 with spray between the gears. I run a 3000 stall in my 700R4 and it is really tight. Tranny is fully built with the addition of the sonnax billet servo, .570 pressure valve which I installed last year and 4th gear holds very well in the 1/4. The key to making these trannys last is pressure. I have yet to blow one up. I've had mine for 7 years, with one fresh up for the 3-4 clutch pack. With a 125 shot I've gained 11mph in the 1/8th so far, but I'm running a nitrous cam. I would recommend running a lot of compression if you want to be fast N/A. I lowered my compression from 12.5 to 10.7 and the car is a dog N/A.
