The 1972 Corvette

1972 Maroon Corvette Coupe

The 1972 Chevrolet Corvette was changed very little from the previous years, mostly this was the last year for some major things. '72 was the last year for chrome front bumpers, side bright "egg crate" grills, and the removable rear window. It was also the last year for performance options RPO LT1 and RPO ZR1. Although both codes would be brought back in the '90s, one as an engine model and the other as the "King of the Hill". The M22 "Rock Crusher" transmission was not available this year. Unfortunately due to emissions and octane requirements horsepower was down this year but not by as much as the specs show. This was the year that horsepower specs were changed from gross horsepower to net horsepower. Before 1972 horsepower was measured on a blueprinted engine without any accessories such as the alternator, A/C, pb etc.. In 1972 the engines were rated with all accessories and the exhaust system which caused the horsepower of the same engine to be rated substantially lower.
