Who runs a 273ci drag car and whats your combination

hi, first a correction, the 273 valient does not run stock, it runs super stock!!
there's a big difference between the two. now, years ago, I ran a stocker 273 dart, it went 13.31 @102.33. today, there is a valient running stock, it has went 11.90- 12.0 . just food for thought.
