Larry, I have run a lightened steel drum that I do vs a ATI aluminum one and there is .08 difference in my V-6 Camaro that has about 75 -100 more HP and a couple hundred pounds more on you Super 10. I spin both to 9600 on the shift and 9400 through the traps. Remember it is sitting still as long as you are in first gear. when you release the band around it and apply the Hi clutches inside it, it has to spin up in RPM to input speed. I've never had on fail. I do use an aftermarket steel hub because the aluminum ones get eaten up by the clutch plate splines. The weight difference that close to the center of the rotating shaft mass makes very very little difference.
Alan... Larry does not want to be fast. His goal is being consistent and above the 9.99 ET cut off.
You spend a lot less money when you stay away from that magic E.T.
