Print Friendly and PDF



Below is a listing of 1974 Corvette production numbers with related RPO codes and performance numbers.

Model Year Highlights:

  • 1974 was the last year for the big block Corvette.
  • The chrome rear bumper from 1973 was replaced by an all new rear bumper on the 1974 Corvette which was composed of a urethane-plastic skin which covered an aluminum impact bar.
  • This would be the last year for Corvettes to be built without catalytic converters.
  • For the coupe, shoulder belts were now incorporated with lap belts to form a one piece seat belt.  For the convertible, shoulder belts were still optional and still kept separate from the lap belts.
