Howards Cams™ Street Force™ Hydraulic Flat Tappet Camshaft & Lifter Set
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° 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.
Note: Always use Camshaft Break-In Lube with all new flat tappet cams.
