Looking for a non-spread bore Carter 4v for a 273ci. I believe the code is 4120. That is the only code I can find for the 273 and that is for a 1966. This if for a Commando 273 in the 1965 Cuda. Thanks for your help.

For 1965, a 273HP used either a Carter 3853 for manual transmission or a 3854 for automatics.
