Why Run the 825HP Marine Cam?

• Larger turbochargers
• S400 and other performance turbo setups
• Upgraded injectors
• Higher-horsepower ECM tuning
• Performance-oriented street and competition builds

It retains genuine Detroit OEM construction while giving performance builders access to the cam profile used in the 825HP marine application.
