Is there any real way to identify a torque converter without any real identification on it, aside from a few stamped numbers?

I have one in the car, and one out. Both for 700-R4/460L trannies. No company tag or anything, just some stamped numbers. Is there any easy way to identify who made them, and what speed they stall at?

If they are 10" or smaller it's a stall. No way to tell.

Anything bigger is probably just a stock stall and it depends on the application it was designed for ... 350, 454... etc will have different stalls... while yet the same converter will stall differently behind said 2 motors.

I don't know of any way. Many of the aftermarket manufacturers start out with a stock convertor case too. So they would look completely stock from the outside.

Alright, so an unused but undocumented converter isn't really worth anything then, is it?
