I have a 1970 455 GTO and the manual tranny is built POK31B and my car is built 11A - does anyone know if that is too far apart to be a numbers car (90+ days - unless I am wrong on something)? My tranny does have the VIN stamped on it and it matches the car (can never be sure the VIN stamp is original can you?).

If the tranny has the car's vin # stamped into it, then you can assume it's the born with tranny and it's #s matching.
:agree

I wouldn't worry, I believe there were around 4,150 455 GTO's built in 70 and probably fewer than half with the 4-speed.

Am I reading the code correctly?
P= Muncie
0K31= July 31, 1970
B= Muncie close ratio 4-speed

Yes, correct, car was built in first week of November - so 90+ days in advance the tranny was built (July 31). Just seemed like a long time before the car was built. I do not have the car yet - so have not had a chance to run all the other build dates to make sure that it all makes sense.
