I have a 91 chevy silverado reg cab stepside 4x4 pickup, and i was wondering what it would do in the quarter mile. The mods are hooker comp long tube headers, true duals with cutouts and glasspacks, open k&n, mild crane cam (or so the previous owner says), 700r4 with b&m shift kit, rear 3.73s, jegs igniton module, jacobson ignition box, and a helix throttle body spacer. And by the way, i raced my old 2.8 85 camaro and took it, although it had me off the line, but im just curious what you think it could do in the quarter. thanks


By the way, the exhaust pipe is 3in in diameter, not exactly sure of the header pipe size though

A few years ago on my 88 gmc i had a350 with a edelbrock manifold and cam, headers, flomaster with a 3 inch single pipe, msd 6al, 2200 rmp conveter, **** kit and 4:10 with a eaton posi out back i ran a best of 15.5
That should be clost to your time.
since then i added a xe 268 comp cam, vortech heads air gap manifold and removed the tbi and went with a 670 street avenger and ran a 13.89 at 97.xx mph and i still feel i can do better with some more tuning
