Stock springs cannot be used. You need high-pressure springs matched to a .560" lift to prevent valve float at 7000+ RPM.

Because this is a high-performance mechanical cam, there are several "must-dos" for installation: 110922 001-1PON20:34 Min

It is a "tight lash" cam, which helps reduce valvetrain noise and wear compared to older mechanical designs. Critical Installation Requirements Stock springs cannot be used

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).

It is optimized for mid-to-top-end power. The 106° LSA provides a "tight" power band that hits hard in the middle of the RPM range, which is ideal for coming out of corners on a track.

Howards Cams recommends provisions for increased oiling to the valvetrain to ensure longevity under racing conditions.
