physical size of the performer is same as factory & shaker should line up fine... but performance wise it is different, has smaller runners & does not flow as well as a factory cast iron intake. main advantage is weight. you can gasket match the factory intake or even send it off fo CNC porting & it will outperform a performer & be just as good if not better than an RPM.
the holley street dominator is a single plane intake & will perform better than the performer, shaker should fit ok as well. the tomahawk is a china copy of the street dominator, actually was cast from a ported street dominator, they are a good intake for the price but should be used on cars with performance upgrades, a single plane will hurt low end throttle responce compared to a dual plane.
