what mods should i be using for my 94 z28 to get to the mid 13's? as of the last time i went to the track, bone stock, i ran a 14.6 on street tires and without stalling ( dont know how). since then i have installed the K&N fipk, flowmaster exhaust (3 inch), cut out, air foil, HPP3, and ive also descreened my maf. have MSD wiring aswell. i dont know what i might be running now. have some 3.42's but not installed, im thinking of selling them. any help would be appreciated thank you

 

A set of sticky tires and a decent set of headers, possibly a gear swap, and you're in the mid 13s easy.
