Can anyone tell me what these numbers mean. I am hoping it came out of a 1969 SS camaro.

BM is consistant with that used in a 1968 and 1969 Camaro and Nova as a 3.31 ratio. 

BM - 3.31 ratio
11 - Noc
02 - Day
G - Axle plant code for Chevrolet Gear & Axle
1 - 1 st work shift on that day

No need to post the same question on both this board and camaros.net. You'll get good answers from both places.

With all respect, some CRG members may not frequent the other board and would learn from the post here.
