Okay Gents, I bought a used TH400 and the guy I got it from did not know what the stall speed was (if any?). I was wondering- how do you tell TC's apart, one from another? There are some numbers stamped on it, but no brand name. Also, the one I had on my old tranny was smaller and a different color than the one on the tranny I have now? I appreciate any help.

usually the mfg. will stamp their part # on the convertor.
At least B&M does..

Do you understand that EVERY torque converter has a stall speed; and that the stall speed is determined by the way the converter is made--but also by how much torque the engine has.

A converter that stalls at 2,500 rpm behind one engine may stall at 3,500 rpm behind a more powerful engine.

It's gonna be tough, might just hafta put it in, to see what it does.

Where in Washington are You? I'm up in B'ham, look in the NW forum, under cruise in's.

Lot's of NW guy's in there.

The one in my th400 was orange and about 12" across. Came with the tranny. No ideas what brand, but was stock stall speed like. I put in a B&M 2400 one, and it was blue and about 10.5 " across. Sorry, no idea what #'s, if any, were stamped in it.

smaller converters usually have more stall

Well guys, I ordered a new B&M TC off of Summit. It has a 2400 stall rating. It's going behind a SBC 400, and I have no intentions of racing it, so it should do. BTW-Dave, I live in Spokane Valley. I messed up the pump and TC on my tranny by installing them on the engine without frst properly seating the TC in the pump (WON'T do that AGAIN). It was a costly mistake.........Thanks guys for the help!
