Lift pump, built tranny, and a GOOD EFI tune will get you low 13's, maybe 12's my friend.

Get yourself a good set of gauges, and a PPE or Quad S2. That'll get you 14's

no worries. not everyone has a large budget.

yes, best case scenario, you get efi, trans, and lift pump. no need to go throwing numbers out in public, but you can pm me and i will tell you what i have in my truck considering it is just being finished up this week.

but as crazy crew said, get a good tuner, and some gauges. and you will be moving closer to your goal if not meeting it.

the shift kit for the 5 speed isnt worth it. a good tune and boost valve is just about all you should need. i had two of my friends running in the high 13's in the 1/4 with tuning on a stock trans.

Just turn off the OD when you push it hard or let up when it starts to shift into OD that is the only time I ever limp the tranny in mine.
