Low 12=upgrade trans sooner than later. You won't make 11s on your 2k budget. The tranny will pretty much blow it. If you want mid 11s reliably I'ld go for a rebuilt trans with hard parts, a Pat's 12" 2800 stall for your TA49, 60lb injectors, alky, TT chip, drag radials, free flowing exhaust, lower control arms. Tune for 27lbs and work on launch. 11s are not "easy", if it was you would see everyone with 11s in the sig. Takes money, all systems functioning correctly and matched, patience and time. For sure it can be done for less if you do most of the work yourself. You may find used injectors, chip and alky kits with so many switching to E85.
