i am wondering how far off the cast dates on a Muncie tranny and a cars build date can be example a car built in September 69 what would be the earliest tranny used???

Most likely the tranny wouldn't be more than a month or two prior to the car's build date; "typical" would be more like a month or less. :thumbsup:

I sold a 1968 Camaro COPO/9737 awhile back that was an O7E build date with the assembly date on the tranny Feb.23! This is about 5 months.. (This is backed up with a P-O-P) So anything is possible from the factory

ok thanks guys i have my VIN #number stamped in my tranny and the build date of the car is 09E and the tranny stamping is P9K09A so thats a two month difference so thats an approx 2 month difference. i was just seeing if this was propper i was 99.9% sure cause i have owned the car since 75' thanks guys this site rocks!

My 69 L-78 has a build date of 11D...Engine build date of 11/22/68
