Howards Cams 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 4 requires an improved intake and exhaust. A good street 2800-3200 converter is also needed. The addition of small tube headers, a good ignition and lower gears makes this combination a lot of fun.
Note: Some applications may require a vacuum canister or pump.
