Ford's 4.6-liter Modular V8 is a great engine design. In fact, it's so great that it can be found in millions of cars, including the Mustang GT.
In order to help this blue pony stand out from the crowd we're installing a pair of Comp Cams Thumpr Cams. These cams offer the best of both worlds: they have a great sound and make more power too. We installed these cams at the Pro-Dyno shops in Fort Mill, SC, and were done before lunch, and it's a job that can be handled by just about anyone with a fair amount of mechanical know-how. The Stage One cams are designed to work with the stock valvesprings, so we didn't change 'em. But if you are looking for a little more grunt, Comp offers options that are more aggressive and valvesprings to match. And except for swapping out the springs, the process is the same.
Special thanks to Pro Dyno.
