Nitrous would be the cheapest way to go and could put you into the 11's with a 150 shot.

^^^what they said.

or u can do it the right way. build the car completley. with a complete setup. full bolt ons, full suspension, a little weight reduction. and BAM! Mid to low 12's (see sig) then if u really want to go fast add a cam, or cam and heads. or spray. or both! then u will have a COMPLETE car.

You need a bigger stall.. like a 3600. Id assume you have LT's already. You can run 12's with full exhaust, gears and Dr's. I went 12.93 with just those mods. Dont listen to alot of guys on the forum that tell you to solve your goals with a cam/bottle. You should be solid for 12.9/13.1 with DR's.

Try this one before you start digging into it too much, just as a baseline, try changing the trailing arms and your tires first and see what that nets you, then work on power and weight. You'd be real surprised what you can do with the same power level when you put it to the ground more effectively.
