582 HHR Shafiroff Dyno
Here is a video of my 582 cu-in big block chevy being Dynoed (Feb 14, 2011) at Scott Shafiroff"s engine shop in Long Island NY. The motor made 753 hp at 5700 rpm and 723 ft-lbs of torque at 5,100 rpm with 93 octane fuel. I just installed it in my 1970 Chevelle SS and it is very stout! I was very impressed at how smooth and balanced the motor is. Great experience if anyone is thinking of going this route. Great folks at Shafiroff's :)
