The end is near...
Road Test magazine got 14.56 and 14.68, with an auto car.
One thing to consider, they didn't have the same timing systems for accurate results in the 70's. If Jim Bob hit the timer a little bit late, the car looks quicker. Just like my GPS drag timer said my 4300lb car with an RV 440 ran a 12.12 quarter mile time. Sure wish it did.
