The 4 door sedan breaks at 18.49, making it a natural CF/S, if it's the 132 horsepower factory rated version. It can also run in BF/S and DF/S (sticks and automatics run together in FWD in NHRA, with the stick cars carrying a 100 pound weight penalty. In IHRA, it's a natural DF/SA that can also run CF/SA and EF/SA.
As far as the tech questions, I will defer to someone more knowledgeable than I. If you want, send me an e-mail and I can help put you in touch with some people that can help you.
"Full stock dashboard, including instruments, fresh air ducts and controls must be retained. Heaters/air conditioners may be removed; controls must remain in dashboard. Tachometer, pressure gauges, etc optional", per the NHRA Rulebook .
