Howards Cams Street Force Hydraulic Flat Tappet Camshaft
Designed for the street performance enthusiast. They feature true street performance with little or no added maintenance. These grinds feature lobes designed to be easy on the valvetrain, and add useable torque, horsepower and throttle response. They also have 112 degree lobe separations to help maintain vacuum. Street Force 1 cams are great for engines with minor or no additional improvements. A good dual plane intake and dual exhaust is great for additional performance.
Note: Some applications may require a vacuum canister or pump.
