Gearing question

Changing the gear really won't change much in the ET but would probably help with MPH if you are running out of carb and cam, 1.58 60' is about normal for a low 12 car. I don't think you are going to improve much here with any gear change, although it does seem like it is over geared a little. Shedding weight is the easiest way to pick up ET, 100lbs = .10, removing weight from the front or changing your front to rear weight distribution will pick up ET also. I thinking more inline with a 4.30 or 4.10 gear.
