Show original supplier description
The COMP Cams 283THR-109 Mutha Thumpr camshaft is engineered for LS1-based engines seeking a significant performance upgrade. This hydraulic roller camshaft is part of COMP Cams' signature Mutha Thumpr series, known for delivering an aggressive, muscle car sound. With a 109-degree lobe separation and an advertised duration of 283/303, this camshaft is designed to enhance power across the RPM range. It is specifically intended for LS1 applications within the 1997-2013 C5-C6 Corvette models. Additionally, it is compatible with a broad spectrum of GM LS engines, including displacements from 4.8L to 7.0L (LS1, LS2, LS3, LS4, LS6, LS7), making it suitable for both car and truck applications. This camshaft is a performance-oriented component that will alter the engine's powerband and sound profile. For optimal performance and reliability, it is recommended to consult COMP Cams' specific installation guidelines, which may include requirements for upgraded valve springs, retainers, and potentially ECU tuning to take full advantage of the camshaft's capabilities.
