I just bought a 72 Ford Q Code 351C and the original C6 that was with it. It included the torque converter and the guy claimed it is a 3000 stall. I'm looking for a way to ID the converter to see if it is actually what he claims it is.

Thanks.

The only way is to install it or cut it open.

Can you find any identifying marks? Is the converter natural or painted?
Do you see a number anywhere...

Not going to find a stock 3000 stall converter. Might be aftermarket.

The converter is natural, no paint. The only engraving I find is "30" stamped on the transmission side.
I get conflicting remarks about Ford using a 3000 stall converter behind the Cobra-Jet motors, even on the many websites I can get info from. Doesn't seem to be any way to prove it.

Thanks,

Should have been a #67 or #69 to be a real CJ converter per the MPC.

Don't worry, there were never any 3000 RPM converters stock from Ford.
Two ways to verify your stall:
1) Cut it open and look -- needs an expert in torque converter design (see our banner sponsor)
2) Put it in the car and do a brake stall per the Ford test sequence.

The factory stall converter behind the CJ motor used a smaller bolt pattern than any other 351. I believe the bolt pattern was 9.5 inches (like a pinto converter)give or take a smidge and it used a one of a kind flywheel. The stall speed was more like 2400
