Not a chance in hell they were going that fast. Its not physiclly possibly with the gearing you can get for the car. With a 2:50 rear (thet highest made and pretty rare), on paper that works out to 139 at 10,500. Thats on paper-I dont think you could get them near that fast at Bonneville-and I wouldn't think about going that fast on a 73
inch wheelbase.
