Valvetrain stability is a critical concern for engine builders, as instability can lead to significant power loss or engine failure. Addressing this, Callies Performance Products has integrated its entire camshaft manufacturing process in-house, eliminating the potential for errors associated with multiple suppliers. They utilize advanced Landis CNC grinders for precision shaping and employ high-accuracy inspection equipment like Adcole and Jenoptik to ensure exact specifications for various engines, including popular models like the Power Stroke and Gen-III Hemi.

To further validate their camshaft designs, Callies employs a Spintron machine to simulate high RPM conditions, testing the complete valvetrain system up to 11,000 RPM. This rigorous testing helps identify issues such as valve float or instability, preventing potential failures during operation.

Callies offers a range of camshaft materials tailored for specific applications through their VTG (Valve Train Group) brand. The Indurocore line, crafted from tough 1050 or 4150 steel, is ideal for high-performance street and racing vehicles, while the Carbocore line, made from hardened 8620 steel, serves applications with higher demands. For extreme builds, Titan Tool Steel provides maximum durability.

Ultimately, Callies is not just selling camshafts; they are providing confidence to builders by controlling the entire process, thereby allowing them to focus on assembly and tuning without uncertainty. This commitment to quality ensures reliable performance in every engine build.
