the threads a little old now but figured i'd add to it incase of future reference :

1973 sedan, built nearly as a daily driver (full interior, big stereo)
running gear :
A12, all balanced, good head work, electronic ignition, twin 40mm webers, 2" exhaust, standard H145 3.9:1 diff, 195/50/15 tyres.

time down quater mile :
17.623sec @ 78.07mph

this is the best time i did on the day.

there was an A15 in a 1000coupe, full racecar that was doing 15.01sec @ 90mph or so.
