    '71 engine code

    Andy,

    According to my NCRS Pocket Spec guide, a 1971 LT-1 engine has a 3 letter code of "CGZ". You may find this code on a rocker arm cover at the rear of the cover, adjacent to the firewall. The letter if stamped on the engine number pad could indicate the engine manufacturing plant. I hope this helps some.

      The C means Chevrolet, 1 is for the numeral of the Chevrolet car line and the next 1 is for 1971. Your 5 is really a S which stands for St. Louis. This comes right out of the NCRS judging manual for 1970 to 1972 vettes. I have a older edition and it really good to have.
