Take a look at this ad from 1968 for Baldwin Chevrolet and Motion Performance. Motion would modify your car so nothing would touch it on the street. Today Motion Chevys bring a pretty penny if you have one.
In 1968, the Phase III Camaro was guaranteed to turn 11.50 1/4 miles times at over 120 mph with a M/P (Modified Production) licensed driver on an NHRA or AHRA sanctioned track. This car was "reliable & streetable" and was able to run these times shortly after being driven off the showroom floor. The warranty on the SS-427 Camaro was 90 days or 4000 miles on the powertrain and 24 months/24000 miles on the rest of the car - excluding all speed options. There was no warranty on any engine that was fitted with "internal engine modifications", such as a camshaft and high rev-kit.
