Back in the 80s me and some friends would rent our local track for test and tune for our street raced cars (and an occasional bike) during the week. Note the empty pit area to the right of the tower. This is a pic of a video i found recently where a young Steve J. set up his video camera and Hibachi in the unused lane (one car per pass only for safety/ins. reasons). He did some hilarious narrating!! This Vette belongs to my then roomate Bud, and is spotless to this day. I think it ran low 12s that day, but eventually went deep into the 10s with a small block and no nitrous. IIRC he did at some point "squeeze" it into the 9s.
