Street True Roller Timing Set - 348/409

The CLOYES Street True Roller Timing Set for 348/409 is designed for builders and enthusiasts who require precise valve timing control on classic big-block Chevrolet engines. This roller timing set is an essential upgrade for anyone restoring a vintage muscle car or enhancing a street engine, ensuring optimal performance and efficiency.

Engineered to replace worn factory components, this timing set minimizes friction and wear through its precision-ground sprockets and hardened steel construction. The roller design enhances load distribution across a larger contact surface, which helps maintain consistent timing and reduces slack, ultimately improving engine performance and longevity.

Ideal for serious 348 or 409 platform projects, this timing set ensures proper valve-to-piston clearance and repeatable performance across various temperature and RPM ranges. Its compact design and lightweight construction contribute to improved throttle response, making it a valuable addition for both carbureted and fuel-injected setups.
