This was for an open house so the public could see what we were doing here in our shop. Fed everybody hot dogs, hamburgers, chips and pop. They got to watch each change and guess the resulting torque and horsepower. We then awarded small prizes or cash to each person that got the closest to the correct horsepower or torque after each change. We made 8 or 9 changes that day including a cam change. The cylinder head swap was the final change.
