torque converter

I have what I believe to be a 325hp+/- 350 motor and 3.73 rear.
I'm replacing the 700r4 trans which was burnt up when I purchased the truck.
Can someone help me choose a torque converter that would be suitable for a street driven 4x4 that would go off road or tow close to never.
Added performance would be great but, reliability is the main concern.

Re: torque converter

What cam does the motor have? That would be the deciding factor for the correct stall. Stay away from B&M converters. They like to explode and take the whole tranny with it.

Re: torque converter

Are you staying with the TH700R4 transmission? If so what year is the replacement transmission you are using?

Re: torque converter

Never had an issue with any of my B&M converters.

For a stock to street mild cam, I'd go with a 2400-2600. I tend to like higher engagement however. 2200-2400 would be fine for others. Brand is "you get what you pay for", so don't go too cheap. Choose a nice mid price range from any major brand and you'll be good. I've had Yank, B&M, Hughes, and a few others and never had an issue with any of the "good ones". I had one no name brand 2600 and had lockup failure (studder step, in and out action) after about 10,000 miles. Replaced it with the Yank and never looked back.

Re: torque converter

I contacted several companies with my specs, and they all pretty much recommended the same stall and gear for the truck I had with the engine I had built. Go with their recommendation - they tend to know what would work best. I am very happy with the 2500 in mine (10.9:1, 350/TH350, cam is 231@050, 108LSA, 104ICL).
