Default what gear to run

01 mullis hard tail.462 bbc.at 13.1 on gas,power glide trans.leaving on the trans break at 4200. it has 3.90 gears now and 36'' tall tires, going the 1/4 miles at 9.62 at 144 but only shifting at 6000rpm and going out the back at 6150..but we are planning on running mostley 1/8 mile.it ran 6.25 at 113 at the 1/8th.the motor came out of a roadster running 8.80s i seen it do it.so i just think i need a little more gear..or shorter tires..any idea's ????? just a side note ,,we only have ran the dragster 5 times so far.. so iam sure it will pick up a little from these numbers.as we tune on it some..but it think it should run more like 8.95s in the 1/4 to 5.50s in the 1/8th....????
