Welcome to CHR

Since you asked for recomendations, as a matter of personal preference, I would go with 3.73's since you are using an O.D. Tranny. That combination really seems like the perfect set-up (read Trade Off) for "street muscle"......to me. Chevy mentioned 3.55's which there would be absolutely nothing wrong with either, just a little less aggressive than I personally like.

Bottom line: Do what you want; but to me, 4.56's would be fun for about the first 20 minutes and then I would be cussing them for the higher RPMs required to run 'em down the highway.

I also think ProZ definitely got it right, the mythical 9 second in the 1/4, daily driver, 1000 point show car, is exactly that....a myth. So, you can either build 'em to run really fast light to light, cruize down the highway or ride in an enclosed trailer. The choice is your's because everything else in-between is a trade-off of somekind or another. Finding the ultimate trade-off (which for you could be very different than it is for me) is really what it's all about.

Cheers, and good luck with the project.
