In BG, Ky by itlgo2 on 2009/12/18 6:53:28 Only 53 of the original ZR1's were built, wish i had one. the tshirt...my design, ZR-1 not zr1 ZR1 & ZR2 (19701972) The ZR1 special engine package was a $1,221.00 option available exclusively with the LT-1 engine option. It was a special racing package that included the solid-lifter small-block engine, heavy-duty four-speed transmission, power brakes, aluminum radiator, and a revised suspension with special springs, shocks, stabilizer bar, and spindle-strut shafts. Since it was competition equipment, the ZR1 could not be ordered with power windows, power steering, air conditioning, a rear-window defogger, wheel covers, or a radio. Only 53 1970-1972 ZR1's were built [16] The ZR2 special engine package was a $1,747.00 (1-year only) option originally planned for 1970[17], but officially released in 1971. It included the racing equipment in the ZR1, but for the LS-6 engine. Per GM policy, 1971 Corvette engines were detuned to run on low-lead fuel, except for the LS-6 454 V8, which was rated at 425 bhp (317 kW) on premium fuel. 188 cars in the 1971 model included the LS-6 engine, with only 12 with the ZR-2 package |
