Zora incessantly worked at convincing Chevrolet that in order to keep the Corvette competitive in racing, greater performance was necessary. This opened the door to bigger brakes and more powerful engines. The 1967-1969 L88 Corvettes, the ZL-1, 1970-1972 ZR-1 and ZR-2 were his eventual offspring.

In 1970 Chevrolet Corvette introduced to the racing world a new street legal racing machine. The racer was dubbed the ZR-1. Production was limited to 1970, '71, and '72. Altogether for the three years, ZR-1 Corvettes totals 53 cars; 25 were produced in 1970, 8 in 1971, and 20 in 1972. Racers saw the natural roll bar effect of the coupe as a safety advantage and, as a result, there are few convertibles.

What is a ZR-1 Corvette? A ZR-1 Corvette is an LT-1 equipped Corvette produced in 1970, '71, or '72. ZR-1's were specially equipped with all the heavy duty racing equipment that had previously been used on the L-88 Corvettes of 1967, ?68, and ?69. The only other Corvettes to receive this special group of heavy duty racing equipment in a package were the ZR-2 in 1971. The ZR-1 included the LT-1 engine, M-22 transmission, heavy duty J56 power brakes, transistorized ignition, special aluminum radiator, and special springs, shocks, and front and rear stabilizer bars.

ZR-1 identification features: (1) LT-1 engine, suffix CTV-1970, CGY-1971, or CKY-1972, (2) J-56 heavy duty brake package with dual pin front brake calipers (power), (3) F-41 heavy duty suspension package, 7 leaf rear spring, heavy duty shock absorbers, heavy duty 5/8″ front sway bar and heavy duty rear spindle struts, (4) M-22 (rockcrusher) transmission, (5) large aluminum radiator with expansion tank (no other LT-1 equipped car has an expansion tank), (6) steel fan shroud, other than 1972?s (most), (7) radio delete (no fenders drilled for antenna). The ZR-1 package could not be ordered with any creature comforts, ie: air conditioning, power windows, power steering, radio, alarm system, rear window defroster, or special trim items like P02 wheel covers.

The ZR-1 cars are the rarest small block Corvettes ever produced. The most common ZR-1 (the 1970) has only 5 more than the rarest L-88 (1967 - 20 units total). The ZR-1 cars are about five times rarer than L-88 cars.

1970 Corvette ZR-1/LT-1 Coupe, 350-370 hp with M-22 special heavy duty transmission and one of only 25 produced. Monza Red paint with Saddle Tan interior in excellent condition. Other rare documented options on this radio delete car include 4.56 posi, F-41 special purpose suspension, power brakes, J-56 special brake system, transistorized ignition, rallys, and Firestone wide ovals. Well documented, rare, and desirable. An affordable L-88 high horse small block. $149,000.00

1972 Corvette ZR-1/LT-1 Coupe, M-22 4 speed, numbers match, 67,007 actual miles. Elkhart Green paint with Black deluxe interior. Very nice cosmetics of what appears to be mostly original paint and interior. Also has detailed chassis and engine compartment. Optioned with power brakes, leather, transistorized ignition, 4.11 posi, shoulder harness, A.I.R., heavy duty suspension, J-56 brakes, aluminized exhaust, seat belts, tinted glass, rallys, and Goodyear F-70x15" blackwall tires. Most all factory correct type components including the smog system. Documented with the tank sticker, warranty pamphlet/P.O.P., owners manual packet, sales brochure, and most delivery pamphlets and cards. Super rare ZR-1 and 1 of only 20 produced for racing by General Motors as these cars were equipped with no radio, M-22 special heavy duty transmission, heavy duty J-56 brakes, T.I. ignition, special aluminum radiator, special springs, shocks, and front and rear stabilizer bars. Looks, runs, and drives excellent. An affordable L-88 high horse small block. $139,000.00

One of these, the green one, was just on the block at Mecum. Bidding got up to $200,000 but did NOT sell because the owner had the reserve set at $205,000 and wouldn't budge.

Had it sold, it would have been the top seller of the auction so far.
