COMP Cams Camshaft CS 305Qio8

If you're looking to get more out of a larger displacement or high compression Small Block Chevy engine, this COMP Cams hydraulic roller camshaft is a solid option. It's designed for applications that can handle a more aggressive profile, specifically those running 3500+ RPM stall torque converters. This camshaft is built for engines that need to breathe deeper and perform at higher RPMs.

This camshaft features a 4-pattern design, meaning the intake and exhaust lobes have different profiles for each bank of cylinders. This allows for fine-tuning of airflow and cylinder filling, which can lead to improved power delivery across the RPM range. The duration figures are 253 degrees intake and 263 degrees exhaust at 0.050 inch lift, with a lobe separation angle that supports its performance intentions. It's intended for use in OE-style roller camshaft setups found in many 1987 and later Small Block Chevys, excluding LT-1 and LS1 variants.

This camshaft is recommended for builds aiming for significant power gains, especially when paired with other performance components like upgraded cylinder heads and a suitable intake manifold. Ensure your engine setup, including the valvetrain and torque converter, is compatible with the demands of this camshaft to achieve optimal results and reliability.
