Proflow''s Hydraulic Roller Camshaft "Sloppy Stage 1" for GM LS series V8 engines (LS1, LS3, etc.), designed for enhanced power with a noticeable but streetable idle, offering .560" lift, 216/220 duration at .050", and 114 LSA, making it ideal for performance builds seeking mid-range to top-end power without sacrificing too much low-end torque, though it requires specific LS engines without Active Fuel Management (AFM) and often benefits from upgraded valve springs and a 3-bolt cam gear conversion.
