Any small tips to help ET?

Your car is pretty much what i started out with a few years ago i got mine to run a 13.90 and i had a stock convertor, stock exhaust manifolds, mild cam 1.88 valves, 235/60 M/T ET Streets and a 3.91 gear and shifted at 5600 rpm. i know with some tweeking you can get it mine is a daily driver also. The main thing that helped mine was 3.91 gear it had a 2.09 sixty foot at 98 mph
