Ok I have no speedo. All I can say it was TOO fast for the car and it was still pulling hard. 327 SBC/7000 redline-hp unknown, T-56, sixth gear, 5700+ rpms, 225/45/17, R200 ratio unknown. I don't think it could redline top gear, and it shoudn't anyways, but this car is very capable of doing 150 mph.
