First congrats on the getting the car. If eventually you're gonna go with forced induction I would say 4.10's. 4.30's and a blower if a weekend car. Get the gear, O/R H pipe, drag radials, pullies, and a JLT CAI and you'll be in the 12's. Don't fear the gear. I had 3.73's and 4.10's and they were great....for about a month. For n/a 4.30 or 4.56 is the way to go. I'm thinking of going up a gear if I "massage" my intake some more. If you have any questions feel free to shoot me a PM. -Mark
