Butch , who knew . My first ride was a 67 stang . I tinkered with it but never made nice car. I was into autocross and seting up the early stangs right can put you at the front with only the best 240's , new z3's keepin up. I taped a 65 ( highly modified but not race or tube or any straight race stuff) with 289 dual quads and 4 spd hit 90 in first gear and it would pull a little over 1 g without comin loose , ah the good ole days.
