Camshaft, TPIS SBC Hydraulic Flat Tappet Cam, .495/.495, 280/280, 112 LSA, SBC up to 1986.
Essentially this is TPIS' flat tappet version of their ZZ409 cam. Very nice daily driver with a slightly choppy idle. Very good mid-range torque cam Note: Flat tappet cams needs zinc in the oil, especially during break-in. Use a zinc additive or oil with zinc in it such as Joe Gibbs or Mobile1 racing oil for valvetrain longevity.
