sub 12s? as in 11s? you'll need quite the list. full bolt ons as in cold air intake, e-fan, underdrive pulley, longtube headers, free flowing mufflers or go with e-cutouts, 170 t-stat, torque converter, 4.56 with limited slip or tru trac, custom tune by either Jay Greene or Hemifever, A/F ratio gauge, cam, ported big valve heads. Add forced induction of your choice, supercharger, turbocharger, or nitrous.
It aint cheap... lol
