Proflow's LS Hyldrilic Roller Camshaft is a popular hydraulic roller camshaft known as the "Sloppy Stage 2" for GM LS engines . It's an aggressive street/strip performance cam, offering a choppy idle and strong mid-to-upper RPM power, ideal for boosted (turbo/supercharged) or naturally aspirated LS builds but requires custom tuning and potentially a 3-bolt conversion or VVT delete.
