Re: 1971 LS6 Chevelle SS Production
They were certainly built for road-testing. Motor Trend tested one with two aboard and 3.31s in their October 1970 issue saying "The new low-compression LS-6 lacks the punch of the original SS454 we tested last fall, running .9-second and 9 mph slower in the quarter..." It went 14.7... I have the issue, looking at it now.
The 'Hi-Performance Cars' Supercar Annual changed to 4.10s - they went 13.65. I do not have this issue so I do not know if it is the same car in the motor trend. The press pool may have had a couple cars.
So the test car is at least one, maybe two.
