I learned on this site that the carburetor was installed on the engine at the assembly plant, not on the engine when it was built at the engine plant. My car was built the 3rd week in Jan., 1969 at the Van Nuys plant; date on trim tag is 01C. My engine stamp is V0110DZ. The date on my 4053 Holley carb is 913, which I'm deciphering as built the 3rd week in Jan., 1969. Could this be the original carb for my engine or is it too late to have made it onto a 01C car? Thank you.
