Howards Cams Street Force Hydraulic Flat Tappet Camshaft & Lifter Set
Howards Street Force™ cams are designed for street performance enthusiasts. They feature true street performance with little to 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. Note: Some applications may require a vacuum canister or pump.
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.
