The COMP Cams Xtreme 4X4 hydraulic roller cam for Chevy small-blocks emphasizes strong low and mid-range torque and is one of the more aggressive hydraulic-roller lobes for street and off-road use. Best results come with headers, 3.55–4.10 gears and a 2000+ rpm stall converter; expect a noticeable idle. Requires a melanized or nitrided distributor gear for compatibility.
