A hole in the blacktop...really?
My grand coupe clocked a 13.0 flat back in about 92.
440, .509 cam, single plane,727 hi stall, 4.10 gear, hoosier DOT. It was a lot of fun. I followed the reciepe on the box. The jobber connection parts had formulas on the back for bracket racing. So I built the 13 second car, and it ran 13 seconds . Go figure.
