Great to see someone with an old FE running it hard!
The time slip looks just like one from twenty-five or thirty years ago of our '91 Mustang coupe (all stock steel body except hood), well except it would have read around a 1.27 or so 60 ft., and generally I had a better reaction time; but we just had a 305 cu. in. (+.020" bore) S.B.F. (inline valve head) E.F.I., 5-spd., with a car weight of about 2960 lbs. and 'naturally aspirated'.
Scott.
