The Corvette ZR1 was first introduced in 1970 as the successor to the L88 Corvette. The car, which could be ordered as Regular Production Option (RPO) ZR1, came equipped with a new, solid-lifter, small-block engine that GM designated the LT1. The LT1 engine, which was manufactured by GM from 1970–1972, was a 350 cubic-inch small block that produced 370 horsepower.
It featured 11:1 compression, a ‘178’ high-performance camshaft and a 780 CFM Holley four-barrel carburetor mounted to a special aluminum intake. Although not as powerful as the L88, the LT1 engine offered consumers an exciting engine platform that could power their Corvettes at and around the racetrack.
In addition to the LT1 engine, Corvettes ordered with RPO ZR1 came equipped with the M22 “Rockcrusher” transmission, heavy-duty power brakes with dual-pin front brake calipers, 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, AM/FM radio and AM/FM Radio, stereo.
