Re: Stock 1/4 Mile performance of ZL-1 or COPO
Dick Harrell tested a 1969 ZL1 Camaro with 4:10 gear and TH400 trans in Super Stock magazine May 1969. The car had open headers, rear spring clamps, and 6 1/2 inch slicks. The remainder of the car was stock. It ran a best of 11.64 @122.15. Harrell commented that the tires were completely inadequate.
