M Code (not q) 4v torque converter

[Paul of MO]

Need some info please.

I have a c6 out of a early 71 M code 4V. There seems to be plenty of info on the later Q code 4V having a higher stall converter but nothing about the M codes.

Does anyone know the factory stall speed of an M code, build date Dec of 70?

The C6 trans is correct to the car with the R servo and appears to have never been out.

The only stamping on the converter is a ford oval and a "65" next to one of the 4 mounting studs. There is a pink paint dab on the converter as well.

It is smooth with no ribbing and 12 inches across.

Thanks in advance!

Paul,

Did some research on this for my 73 Q code. It has the high stall with it and also had a C6. This one is identified with a letter on the case by one of the studs...dont remember but it is a B or C. I also found the letter identification somewhere in the shop manual so knew that I had the right one. Mine is also a 10" diameter and believe the larger 12" converters were the standard NOT high stall converters.
