Your 60 foot times are the proverbial millstone. And the secondaries aren't going to give you a ton there. It will still be a stout street car , but a gear will be the cheapest and quickest way to get that car down track. Some suspension tricks will give you some gain , but if you don't see a 1.7 60 ft. or so , you will never see the kind of time slip that car is capable of.
