Sixties Posted January 2, 2010 Report Share Posted January 2, 2010 If this question has been ask and answered in another post, please refer me to that post. The car in question is a 2010 GT500 which is schedule to arrive next week. During the first week a 2.9 SC kit, full headers and an aluminum drive shaft will be installed. I'm hoping for HP between 750 and 800 at the fly wheel. I'm looking for a gear that will cross the line at ~5800 rpm. Since tire diameter is a factor, I don't know what gear will fit this requirement. In the past, distant past, even 4.11 gears would not have been low enough. I am planning to put drag radials on the back but have no idea of wheel or tire sizes. I'm considering 3.73, 4.10, 4.30 gears. I don't know if a 3.90 gear exists but that also might work. My only interest is 1/4 mile performance. Any thoughts on this topic will be appreciated. Thanks. Link to comment Share on other sites More sharing options...
