sometimes, I look at the numbers comparing stock and race versions of a car, and wonder why the stock one had more parts, but accomplished less. Example, 1969 Z 28 with the 302

Horsepower and torque of a Z/28 302 engine make for a customer, with cross ram dual quads?
377 horsepower at 6000 rpm and 355 ft.lbs torque at 4500 rpm

What about one of the Z/28s that raced in the 1969 Trans Am series?
 486HP with a single 4 BBL
