MAGNUM HYDRAULICS<br />
Magnum Hydraulics are to be used in high performance applications with a minimum tappet diameter of .842”<br />
(Chevrolet) or larger. These lobes are more aggressive in their design characteristics and can be used as intake or<br />
exhaust lobes.They are a bigger brother to the High Energy family and are frequently used by the budget minded<br />
Saturday night racer. They also provide a very "throaty" sound.<br />
