The ZR-1 (1970-'72) Street Legal Racer... 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. All together 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; maybe only 20%. What is a ZR-1 Corvette? A ZR-1 Corvette is a special purpose built LT1 engine package in a 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, heavy duty close ratio transmission, heavy duty J56 power brakes, transistorized ignition, special aluminum radiator, and special heavy duty springs, shocks, and stabilizer bar. 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) 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) heavy duty close ratio 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. You can buy a ZR-1 from ProTeam: 1970 - 1006M note: portions of this article were taken from Vette Vues Magazine, Have a specific question or request, email terry@proteamcorvette.com |
