I have a 91 gt with a cam, gt 40 heads, headers, rockers, and 3.73 gears, it still has the stock upper and lower intake, what would be better to install, im looking at the ssi bbk intake vs. the cheaper cobra intake, its my daily driver so what would be best to add. im not thinking of taking it to the track i just want it to keep up with the cars around here where i live, basically ss camaros, trans ams etc. Any help will be appreciated, thanks for looking! I also have a set of 23lb injectors not installed that i was thinking about adding.
