They never ever really supertuned a car. They would make one pathetic blast down a track and then add headers, then after that set the timing and curve, then change jets etc etc, instead of sticking with it to see what it could do.

So true...but, I have found exactly 1 instance where they tinkered with a virtually stock car to see what she would/could do. It was done by SS&DI, Nov '68, and was the start of their "Project Camaro" series. Here's the run down...
Test: '68 Z/28, ordered with 4.30 posi, spoilers, M22, power disc brakes, and floor mats. Total cost: $3,686.55
- Heater assembly & AIR pump removed, due to the car being in an accident just prior to starting the project. Everything else was rebuilt as it was from the factory.

- Valves run, new set of AC43s, car cooled down..it then runs a 13.99 @106.50, then a

- Dropped air pressure in tires to 22psi, installed Champion J6J plugs, and timing reset to 40 degrees. Made 3 more passes, best of which was a

So, in a matter of a few hours, they managed to knock off 6 tenth just by fiddling with the car. And that's mid 13s with a pretty strong MPH, on the skinnies, and through the stock exhaust manifolds. Unfortunately, most people spend the few hours they *should be* tuning instead installing a set of headers or a bigger carb or...
