Story
1972 Chevrolet Corvette
The 1972 Corvette kept the coupe and convertible forms of the chrome-bumper C3, but its engine story is easiest to understand through the new SAE net ratings. The standard 350 was advertised at 200 hp, the solid-lifter LT-1 at 255 hp, and the LS5 454 at 270 hp. Those three engine paths belong on one model-year page; badges or an installed engine do not create a separate model identity.
Engines and driveline
The standard 350 used a Rochester Quadrajet and could be paired with the standard wide-ratio four-speed or Turbo Hydra-Matic. The LT-1 retained solid lifters and a Holley four-barrel and was manual-transmission only. The LS5 used the Mark IV 454 and was offered with wide- or close-ratio four-speed and automatic combinations, except that California availability was restricted. Positraction was standard, with ratios selected by engine, transmission, air conditioning, and economy, performance, or special-purpose requirements.
ZR1 and chassis
Twenty buyers ordered ZR1, a special-purpose subset of LT-1 production. Its identity depends on the complete package: LT-1 engine, special close-ratio transmission, cooling and ignition equipment, heavy-duty suspension and brakes, excluded comfort equipment, and records. The regular Corvette already used independent front and rear suspension and four-wheel discs; J50 added power assist.
Body, paint, and cabin
The 1972 model was the last Corvette with chrome bumpers at both ends. Coupes used removable roof panels and rear glass, while convertibles used a soft top and could take an auxiliary hardtop. Ten regular paint rows are published, but their 26,949 total is 55 below total production. Special-paint and primer cars, including the documented executive-order black convertible, explain why a regular color chart cannot authenticate every body.
Production and verification
Chevrolet built 27,004 Corvettes: 20,496 coupes and 6,508 convertibles. Published engine orders list 1,741 LT-1s and 3,913 LS5s, leaving 21,350 standard-engine cars by arithmetic rather than a separately printed row. Published transmission orders list 1,638 M21 close-ratio units and 14,543 automatics, but do not directly enumerate every standard wide-ratio installation. Verify an individual car through the VIN engine letter, body and sequence, trim tag, tank sticker or broadcast records, engine and transmission stamps, castings and dates, axle, chassis hardware, paint layers, interior, and restoration history.
