A quick but not too abrupt coming off the clutch without feathering it along with an equally smoothed transition on the throttle without wheel spin or bogging is the goal to shoot for.

With street tires you can't expect too much better than about a 2.0 60' time.

You can improve your launch and 2nd gear with drag radials - Mickey Thompson makes a 305 that will fit the stock 19" wheels.
They will stop the hop as well...
They are made of softer compounds and have a softer side wall.
Find another set of 19" Z wheels and put them on when you want to go to the drag strip.

What was your trap speed ???
