You must use oil with high ZDDP content or a ZDDP additive during break-in and regular operation to prevent the flat tappets from "wiping" the cam lobes. Performance Characteristics You must use oil with high
This camshaft is designed for engines (1955–1998). It is a "Mechanical Flat Tappet" style, meaning it requires manual lash adjustments and is typically used in higher-RPM racing applications rather than standard daily drivers. Technical Specifications Operating Range: 3000 to 7200 RPM. Duration @ .050": 252° Intake / 260° Exhaust. Valve Lift: .540" Intake / .560" Exhaust. Lobe Separation: 106° LSA (Lobe Separation Angle).
Stock springs cannot be used. You need high-pressure springs matched to a .560" lift to prevent valve float at 7000+ RPM.
