Over the summer we experimented swapping my 3.73 gears out with Chris Wise's 4.10s. I know this doesn't make much sense, but I actually got better traction on the street with the 4.10s. Where the 3.73s would tend to snap the tires loose, the 4.10s turned just enough slower to grip the pavement and squirt the car forward.
I'm reffering to nailing the throttle from a 25-40 mph roll, not a standing start. From a stop both gears feel about the same on street tires..meaning that with more than 1/3 throttle, you just sit there with tires spinning instead of moving.
The 4.10s were better on the track (with slicks), but I didn't like them on the highway or the street and we swapped the pumpkins back so I've got the 3.73s again. Chris's car ran pretty much the same ET and MPH with 3.73s as it did with 4.10s, but his rpms were lower thru the traps.
So it really depends on what your looking for.
