Why does Ford have to use 3 extra cams and 16 extra valves to compete with camaro's V8's?

And they even had to go supercharged until 2011 to beat an LS1 Camaro.

Because Ford's cars are a lot cheaper than Chevy's.

Bc Chevy had a larger motor.

The Camaro has an extra 1.2 liters of displacement.

"And they even had to go supercharged until 2011 to beat an LS1 Camaro. "

Nope the DOHC 4.6L N/A, stock for stock is basically a match for an LS1.
