I'm tearing down my 360 to address a spun bearing problem, and I thought I'd try to figure out what converter I have. (I bought the whole drivetrain used, so it's been a detective game.)

The only markings are these numbers on the crank hub: C300 2601.

It has 3/8" bolt holes. It measures 9 1/2" in diameter. It stalls to about 3200, flashes off the line to about 4000, and recovers to 5000 when I shift at 6000. Car runs 11.90's, weighs 3000 lbs.

It has this flexplate (It has a part number on it): B&M 10236 Chrysler SFI Flexplate 6 Bolt Crank, TF 727 w/ 360 CID While on the subject of the flexplate, this flexplate is for external balance. Is that what the cutout is for? Neither it, or the converter have any weights on them. The engine appears to have been balanced. It has KB 190's in it, and there are grinding (belt sander?) marks on the rods. The crank has different holes drilled in it than another crank I have, if that means anything. No Mallory has been added. It has the stock balancer with the offset weight cast in.

I bought it in 2009, and it had been running for a few years is the best guess the previous owner could make. He didn't build it. I just started using it a couple of years ago.

I don't know if anybody can tell you much about the converter. Almost all converter (performance)builders decal/paint some form of identification on their products. The company I worked for, stenciled the part number on it, put a decal on it, and most importantly, all performance converters had a serial number stamped into the body of the converter. With the serial number, we could tell what was done to the converter originally, who the original owner was, and what it was being used for, and if it had ever been sent back to us for work, what we did to it. All 360 converters have weights on them from the factory, but when weights are removed, then the B&M flexplates come into use.
Just a thought on my part, while the engine is out, maybe it's a good time to have the converter taken apart for a cleanout and inspection. There have performance converter builders mentioned by others on this board, so I'm sure one of them must be close to you. Not much help I know, but hopefully others can add to this. Good luck.
