These new stage packages from Mast make big, dyno proven horsepower gains using pump gas. No headaches, no guesswork, just big power. Horsepower gains listed are performed on a chassis dyno resulting in true before and after, at the wheels horsepower gains.
The kit includes:
-L99 VVT Cam
- Phaser plate
-Mast premium nitrided valve springs
Duration @ .050 220/234
This kit when coupled with headers can produce a 68 hp gain at the rear wheels. This cam has a noticeable choppy idle.
