Pro-Filer Performance Products Sniper Big Block Chevy Intake Manifolds

Pro-Filer Performance Products Sniper big block Chevy intake manifolds--the ultimate in BBC conventional port intakes! Available for 9.8 in. or 10.2 in. deck heights, these bad boys are designed with the perfect runner-to-plenum volume to maximize the power and acceleration curves of your engine. They're made from aerospace-grade aluminum alloy and feature cast injection bosses, a 4500-style carburetor flange, four corner water bosses, and your choice of a variety of port configurations. Sniper BBC single plane intakes also feature: * 1 in. cast spacer * Optimized cross sectional area * Precision-cast runners * Recommended for 565+ c.i.d. engines Note: For optimum performance, Sniper intake manifolds should be port matched to the heads. Tall deck models require either a slip collar distributor or a distributor designed for a tall deck block. There is not enough material in the intake floor to safely machine it to use a short deck distributor. Show Less
