Advice to get in mid 12s before for pinks all out!!!

[moncada427]

Hey
I recently registered my shop truck, 72 swb stepside for a knock off pinks all out event in san antonio this june 10. My truck is currently running 13.02... so close to a 12 but ive only run it about 10 passes in the past 6 months. I have about a $2000 budget, $2600 if i sell my cheapo pro comp heads to one of my customers. Nothing has been done to lighten the truck. My question is where will my setup benefit the most in et to achieve a mid 12 without nos.. given the fact i dont mind the streetablility factor and the willing to put a little more in the pot..
Heres what she has:
Drivetrain: turbo 400 w/ shift kit, 3200 cheapo stall, 3.73 gears, 26x11.5 hoosiers, and its ending the 1/4 around 5200 @ 102mph. Lol have 29x15.5 M/T for the street

Engine:
355ci stock truck rods and crank, clearanced bearing tolerances to race
7qt kick out pan
11.93:1 speed pro domes, been running on 93 on the street the past 6 months and been doing fine, c12 at track... gotta love the smell
pro comp aluminum heads with 210cc runner, 2.02/1.60, 64cc "heard they dont flow any better than a vortec head"
Comp magnum cam.. .525/.525 lift, 253/253 dur, 305/305 adv dur, 110 lsa, operating range 3,000 to 7,000, and is not degreed to motor... "possible factor"
professional products hurricane single plane intake that was gasket matched to the 1266 fel pro
750 demon dp
stock hei distributor with tighter advance springs cause compression

So.. different heads, gears, ignition up grade, converter, degree cam....??? Your advice is appreciated.
