How old is Billy now?
Actually, I think the Cobalt might be the new "killer app". I raced my girlfriend's Cobalt at the first Rockingham bracket points race this year, and I believe that just getting it down to minimum weight, dumping the airbox and exhaust, and throwing some 6x20 M/T's on the front, it'd be well under the index! In IHRA, it fits FF/SA, 2970#, 16.30/9.95 index. Probably would be tougher to hit the 1/8th mile index, but I think Chip Johnson said his kid ran 16.40's with his Cobalt, bone stock. Sweeet.
