I thought everyone might like to see some numbers from my very stock 1971 TA, auto, air, 3.08 rear. Obviously not the best equipped car for the 1/4 mile. I took it to the Pure Stock Drags in 2007 right after I bought it- it had 48k miles, was never apart, it even has the original exhaust.
Race 1 = 14.933, 2.355 60 foot 95.96 mph
Race 2 = 14.341 2.159 60 foot, 97.13 mph
Race 3 = 14.393 2.173 60 foot, 96.51 mph
Nothing was done to the car to prep it, I just drove it there and raced. I had also never been down the 1/4, so I'm sure my driving skills left something to be desired. My impression is that most of the cars at the PSD have been optimized to some degree. I was paired with a 72 GSX with a 350. I doubt that car totally stock would have kept up.
