I have a 64 1/2 Mustang... I need to know what the code means that I find stamped on the underside of the hood. It reads 4 1 2 C. Does any one know what this means??

darnit i don't have my decoder book in front of me.

i do believe that the first set of numbers is the model year. the C is the engine code. a 289 2v.

again, i don't have my book with me. i could check real quick though.
