The guys who have a lot of torque (9.5 deck) can make better use of a 3.08 gear. The little 8.2 deck engines (most of them) even with a centrifugal 'charger, they need RPM to make power, and it typically takes longer to get it with a highway gear. I was always happiest with a 3.73, or 3.55 for a driver, with a 2.95 T5. You do have to learn to shift, though.
Drag racing with a manual is fun, at least to me. I'm quicker with an auto though, but nothing beats the challenge (and IMO, fun) in choosing your own stall speed with the use of the left foot/leg.
