best combination

hey everyone, its been a while since ive posted but i recently sold my 1990 na 300zx with 154000 miles and a blown cylinder for $2700, and i now plan on buying a 96 or 97 trans am. my main question is, what is the best stall speed torque converter for an A4 with 3.73 gears? do you think i would have a traction problem with 3.73's, 3000 stall, lower control arms, and nitto drag radials? also, will 245/50/16 drag radials fit on the stock trans am rims? thanks for the advice, ill let u know when i buy the car. o yeah one more question, what do you think the car would run with those mods on a decently prepped track in jersey, im thinking 13.3's
