Kinsler Injected
Ram Air IV for
Nostalgia Super Stock

A customer came to us in need of an old-school Pontiac for a car he'd be campaigning in Nostalgia Super Stock competition. It had to fit the rules — including needing a vintage-looking Kinsler fuel injection system. And our customer didn't just want to compete. He wants to win. So, we put together a 13.5:1 462-inch Pontiac that makes nearly 700 horsepower!
Check out its power curve!
