Bobby DeArmand was the first legal NHRA A/SA to run altitude corrected 9.99 at Boise, ID back a long time ago up
A friend of mine was at that race trying to be the first A/SA to run in the nines also, my old NHRA 1963 Plymouth Belevedere two door sedan 63 415 HP M.W. car was there trying to do the same thing.

Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
