How hard can a 273,run? (street/strip)?

As promised here's a pic of dads 67 belvedere that ran a warmed over hi-po 273 in it! he did well @ Kearney drag way in Kearney ne. in about '78-'79 Hes has awards for the brackets he ran in it clicked off 14.30's all day everyday! (Just as I came into the picture!) I barley remember that car sold it when I was 4 years,old back in '83! But he went with the 273 for one it was cheap & froze up & knew they can be built to run! That's what started my love for the little cast aside 273! Last I new it was in texas somewhere...
Wow , love them old Belvedre , 14.3 is pretty good for that car with a 273 , my friends were running 14.2 to 14.6 with sock 340 Dusters and Darts with a set of headers not much else .
