Torque Converter identification

[nickpohlaandp]

Hi everyone. So today I was looking through the FB Marketplace and someone has posted a torque converter for sale, $100, claiming it’s a 3500 stall. It’s a 12” converter. I’m wanting to run a 3500 stall with my project, and I know I’m going to need to spend at least 10 times that to get a quality converter, but I’m thinking about purchasing this just so I can drive the car around a little bit. He said it came out of his 1990 S-10 with a 383, and it’s too much stall for his liking. There’s nothing remarkable about the converter, it just looks like your average, run of the mill torque converter. The guy selling it doesn’t have any paperwork on it, and the only markings he could find on it are “K3 0 d77”. I know it’s a shot in the dark, but is there any chance that “K3 0 d77” means anything? Does anyone maybe know what this thing really is off of those markings? I doubt this makes much of a difference, but it’s painted in a baby blue color. Thanks in advance for any input you might have.

So I was off a bit on the color. Here's a pic of the converter.

Thanks. Another guy let me know that I don't want to use it. It's a 12" converter, and he was saying that a 12" converter isn't going to stall at 3500... maybe 2800. I appreciate you finding that pic though. Sure looks like a B&M.

The stall speed is related to engine tq, more tq, higher stall speed. So stall 'numbers' are merely a guide.
