Default Re: Best gear for 9.90

While it is true that finish line RPM plays a part, I was convinced a few years back by Eddie Jr, at Select Performance, to go to a 4.56 gear.. not only to enhance his converter set-up, but that I would be surprised by the charge coming off the stop.. I now have 2% to 3% slip in the converter at the top end, and that charge coming off the stop is awesome, and I go out the back door at approximately 7600 RPM with my 565.. I am only 2150 pounds also..

While I was a nay-sayer, until I switched from the 4.30, I doubt I'll go back.. while it slightly increased the RPM, I didn't seem to affect the MPH at all...
