TCI torque converter
I already have a 2004r tranny,although needs to be opened up and gone through,and was looking on marketplace and found a new TCI street fighter torque converter new for sale for $200 and they go for about 600,it’s stall ratings is 2200-2600,which is what I think I will need,for about 350-400 hp,and 3.54 gears. I’ve seen good and bad things about TCI,but,they are a good,quality converter correct,thanks.

I...Had a 11.5" TCI TC long time ago, what a POS boat anchor it was for a 2400. It was very lose and seemed like driving around towing something at light throttle. Now, I have a Yank SS 3200 9.5" and drives like a stock TC until you hit the loud peddle and then yeeha! You would never know it's a 3200. I'm actually going to have the 3200 re-stalled to 3500 for $300 so that it works out perfect with my setup after doing the math and a lot of launches. Best 60' has been 1.7, shooting for a 1.6 or better. Each to their own, but since I actually had one and was very disappointed with it, I would never use TCI again for anything.

Yep,that’s what I needed to know,thanks,and bikespace I have bought a lot of stuff on marketplace,FB mostly golf clubs though,but did recently buy a 1972 GTO on their. A lot of people sell on FB,and it’s actually a good way to get great deals on things,but I guess to each is on.Im by no means cheap,sometimes I wished I was,but if something is new and I can save half the money,I’ll take that everyday.but,you do have to be careful also when buying on their.

Here's a couple , the 27 splines of the 200R4 and early run 700R4's limit converter selection.

Stall speed is a guestimate so call the Converter manufacture not Jegs for best results but to give you a recent example is I just installed a close ratio gear set in my 700R4 and installed a new Torque converter at the same time , I took out the stock 1650 rpm converter and installed a factory replacement S10 pickup 4.3 V6 TC into my 1980 L82 with aluminum heads and Comp XE262 cam , rated stall for the 4.3 V6 was 1950 rpm stall but with my 10 to 1 compression 355 it stalls 2250 to 2300 rpm so that gives you an idea about a 1950 to 2300rpm stall speed guestimate , if I had a really big cam with not much torque down at low rpm then my stall speed would be much lower than the 2300 rpm I have now

On my LS swaps I have used Yank and Circle billet converters. Both have worked have worked well. My builds are fairly mild. So the stall speed is 2800-3000. As said above they drive like a stocker until you floor it.
