The 1970-72 ZR1 package make it one of the rarest small-block production Corvettes of all time. With only 53 units built over three years—25 in 1970, eight in 1971, and 20 in 1972—the first-generation ZR1 is rarer than even the L88 or the 1963 Z06.
Corvettes ordered with RPO ZR1 came equipped with the M22 “Rockcrusher” transmission, heavy-duty power brakes with dual-pin front brake calipers (J56), a transistor ignition, a special aluminum radiator and a heavier-duty suspension package that included bolstered 7-leaf rear springs, shocks and heavy-duty 5/8 inch front sway bars and rear spindle struts/stabilizer bars.
The car also came equipped with metal fan shrouds. Moreover, when ordering a ZR1, the following options were deleted from the Corvette, including: a rear window defroster , air-conditioning, power steering, deluxe wheel covers, the alarm system, and AM/FM Radio stereo.
This 1970 Chevrolet Corvette ZR1 coupe, one of just 25 from that year, was initially delivered to Ed Rinke Chevrolet in Centerline, Michigan. The car changed hands several times within Michigan during the 1970s, later moving to Indiana, Pennsylvania, Ohio, and eventually a museum in Florida. It was refurbished, earning NCRS Top Flight honors in 2014 and a feature in Keith Cornett’s 2018 book Corvette Special Editions.
Finished in Monza Red over a Saddle vinyl interior, this ZR1 retains its original matching-numbers 350ci LT-1 V8 engine, factory-rated at 370 horsepower and 380 lb-ft of torque, along with its M22 4-speed transmission and 3.70 Positraction rear end. Additional features include an aluminum radiator, heavy-duty disc brakes, reinforced front and rear suspension, removable roof panels, 15″ Rally wheels, retractable headlights, and a cabin heater.
