The 475 wheel HP Superformance with a small block that I recently sold would beat the ACR Viper 1st gear to half way through 4th gear(125 mph) without question.

They were doing dyno runs at Hillbank on Saturday, and a SPF with a 550 hp Roush 427R windsor pulled 473hp at the rear wheels. This was on a hot day as well. Either the 427R is putting out more than 550hp at the crank, or the drive train is not taking as much hp as people think. I was suprised at the #. I wish I had taken my car.  |
