I have 4.11's in my Old Vette racecar with a Muncie M22 Rock crusher Talk about close ratio. 2.20/1.64/1.28/1. This car taches 8500rpms on a SBC 327. 540 rwHP (not Flywheel. Car runs high 10's on a road race setup. I have video footage of it on youtube. I used to be the top Vette in the nation back in the early 90's. I use to beat Hobaugh and Thorton. Hobaugh is the current guy to beat in todays world. I don't have to money to bring that car out of retirement- nor the desire. I have other interests now then running the little tight cornered Goodguys baby-autox bullshit(About 1/4 the size of conventional SCCA autox).
