Weight ,weight ,weight .Look for anything to throw overboard especially on the front first off.A scoop and glass hood would be nice ,but dont waist your time if your not gunna make a pan and seal it to the carb.You may not need S/S springs or Caltracs.Im cutting mid to low 1.5 60 foots on 8.5 slicks and 47 yearold 6 cylinder springs .I would spend the $$ on the cam ,heads ,and intake as others have said.You wont really know if you have traction issues till you take it to the track.Subframe connectors are a must .I shaved a tenth off my 60 foot by adding them to my Dart and they only cost me $25.00 to make and a day to weld in .If it will hook now i think you should be in the 12's with what you got now ...
