first time down the track advise?

I broke my 5.14's a couple of years ago and stuck some 3.50 gears in so I could go race and it still ran a 6.39 @ 109 in the 1/8 crossing the finish line in 2nd gear. I am faster now and was thinking about putting them back in and see what it will run now. I am running 4.56 gears now.
