That 1962 valve cover was used on 250HP and 300 HP motors. No sloped ramps on each end on inset ( 62 only 327 valve cover)
only factory air 1962’s had a alternator, all other 62‘s came with generator.
My friend Jim had a 64 with just a 283 4V 4 speed. That little car was fun and quick but the rear was skittish. It wanted to be the front of the car sometimes.
