On Paul's gear chart, look at the 4.10 gear. In fourth at 7K (which is where you want to be in the traps), you're at 130mph. You need way more than 500 crank hp to do that. That tells me, ideally 4.10 gears are STILL a little too tall to be the optimum for the Qtr. Maybe a little more tire, say 255X50X16" and a 4.56 gear might just be the ticket.
Of course nobody, even Pete, has done that. But once you start bolting slicks and skinnies on the car, why not?

Pete's been able to do 129 either w 3.45s or 4.10s.
