Trying to go from memory. I did a project for a Columbus OH dealership.
Off the showroom floor was 12.7. Pipe and DFO 12.4 and after Speed* kit 11.6.
Pretty sure those are the numbers. Did a story on the build in 03 I think.
I found the artical and corrected the times. I could post the story if anyone is interested. Seems like a long time ago...
Jus an ol drag racer...
