Re: COPO 3963512 block. No VIN#
 

Not perfect but a couple good rules to go by when no listings are at hand;

- '70 model year & newer engines have the 3 digit suffix starting w/ a C for Cars and T for Trucks...'69 and older the 2 digit suffix w/ no C or T..

- When a Vin stamping is there count backwards from the end and the 8'th digit is the model year..

Just out of curiosity, are there any known 69 COPO Camaro with 3 letter code, e.g. CMN?

No - the COPO MN code was used for the 1969 427 4 Speed combination and MO for the automatic. The use of the 3 letter code began with the 1970 model year. This included the blocks and the rears.

But 69 Camaro had an extended model year. The later axles were 3 digits and some BB's were too. I have a service bulletin: 400 (meaning 402) engine released for 1969 Camaro. They talk about the 3 digit BB codes. I need to scan it soon.
But I've not seen a COPO with a 3 digit code.
