The COMP Cams CS-268A-R10 camshaft is a versatile profile offering good vacuum, strong throttle response and a noticeable idle while working well with stock manifolds and 2000+ stall converters. It’s optimized for small-block Chevy installations but requires a melanized or nitrided distributor gear; it is not compatible with standard cast or steel gears without similar surface treatment. Does not fit 1955–1957 SBCs with rear-journal oiling grooves.
