Howards Cams Street Force 1 hydraulic roller camshafts are available in 3-bolt or 1-bolt (for models without variable valve timing) configurations. These performance cams are designed for specific Chevrolet Gen III LS-series engines, offering significant power gains over the factory cam. They're intended for street and moderate-race applications and are known for their durability and reduced maintenance compared to older "flat tappet" camshaft designs. Features and benefits: * Hydraulic roller design: Unlike older flat tappet cams, a hydraulic roller cam uses roller wheels on the lifters to track along the camshaft lobes. This design reduces friction and wear, allowing for faster and more aggressive valve timing. The hydraulic lifters also automatically adjust to maintain proper valve lash, eliminating the need for periodic manual adjustments. * Performance enhancement: These camshafts provide improved throttle response and noticeable horsepower gains, particularly in the mid-range and top end of the RPM band. * Idle quality: The cams are described as having a good idle, which means they should not be excessively "lopey" or rough, making them suitable for street use. * Maintenance benefits: The hydraulic operation means easier maintenance compared to solid roller cams, which require regular valve lash adjustments. * What to consider before buying: -- Despite the similar name, these hydraulic roller cams are a higher-performance option than the milder "Street Force 1" flat tappet series and are not designed for the same applications. -- Required upgrades: As with most performance cams, supporting modifications are necessary. Upgraded valve springs are required to handle the increased lift and faster ramp rates. Upgraded pushrods are also recommended. -- Professional tuning: Installing a performance camshaft requires a custom engine tune to optimize its performance and ensure proper engine function. Ignoring this step can lead to poor performance or engine damage.

Howards Cams Street Force 4 hydraulic roller camshafts are high performance models designed for car enthusiasts who want a rough, lopey idle and significant power improvements in the mid-to-high RPM range. Their specific grinds determine each cam's unique performance characteristics. What the specifications mean: * Hydraulic roller: This describes the type of lifter the camshaft is designed for. Hydraulic roller lifters use a wheel-like roller on the end that rides along the cam lobe. This design significantly reduces friction and allows for more aggressive lobe profiles compared to older flat-tappet designs. * Street Force 4: This is a series of performance camshafts from Howards Cams. The "4" indicates it is the most aggressive grind in the series, designed for optimal street performance and mild drag racing. * Performance enhancements: Compared to a stock camshaft, the Street Force 4 offers: -- A longer duration (how long the valves stay open) for more airflow at higher RPMs -- Higher lift (how far the valves open) to allow more air and fuel to enter the combustion chamber * Engine characteristics: The design of this cam results in: -- A noticeable lopey or "choppy" idle due to the valve overlap -- Higher horsepower and torque, particularly at mid-range to high engine speeds * Supporting modifications: Because of their aggressive profile, Street Force 4 camshafts generally require other engine modifications for proper performance, such as: -- A higher-stall torque converter (2,800 to 3,500 rpm) -- An upgraded intake manifold and carburetor -- Improved headers and exhaust system -- An upgraded ignition system ** How a camshaft works A camshaft is a rotating shaft with a series of lobes (or cams) that controls the timing of the engine's valves. -- Controls valves: As the camshaft turns, the lobes push on the valve lifters, which in turn open and close the intake and exhaust valves. -- Engine timing: This process must be precisely synchronized with the movement of the pistons to ensure that the air/fuel mixture enters and the exhaust gases exit at the correct times during the engine's four-stroke cycle. -- Performance: The shape of the cam lobes is engineered to determine how long and how far the valves are open, which is the key factor that determines an engine's power band.
