Detailed Description

Part number SPD-20 is a Melling stock replacement camshaft for engines that need an OE-style grind and factory-like drivability. The cam profile is specified with hydraulic flat tappet lifter type, 1.5 rocker arm ratio, and timing events that support stock engine operation.

• Addressing loss of valve lift and duration from a damaged camshaft
• Replacing a camshaft that no longer matches OE engine requirements
• Supporting proper torque and drivability in factory-style applications
