The original race Engine lifter, solid (also referred to as mechanical) flat tappet Camshafts feature more aggressive street performance or racing profiles and are capable of higher Engine RPM than hydraulic flat tappet Camshafts. As with the hydraulic flat tappet camshaft, the flat appearing lifter bottom follows the contours of the Camshaft to operate the Valve train components at the appropriate time, rotating within the lifter bore in a similar fashion to the hydraulic flat tappet lifter. The solid lifter does not have the internal cavity and piston found with the hydraulic lifter and does not expand or contract with Engine temperature. Because of this feature, the solid lifter requires an initial cold Valve lash setting and then adjustment after the Engine has reached operating temperature (hot lash setting) to deliver the Engines top performance potential. Solid flat tappet lifters also feature a signature performance “ticking” sound, particularly when cold, that many performance fans like.
