My 1969 1/2 440 ‘cuda

All 1969 1/2 440 ‘cudas had the E63 for the engine code which was the designation for a 383. They were than converted to 440’s. I suppose the 63 on the fender well was to let them know the car was to get a 440 engine. Don’t know why they didn’t use the 440 designation on the fender tag or fender well, baffling.
