Top Street Performance Vortec Intake Manifolds

Top Street Performance Vortec intake manifolds are dual plane, high performance units ideal for street performance applications with a design that improves throttle response, as well as power and torque over a wide rpm range--idle to 5,500. They are cast from lightweight aluminum and feature a low-profile for ideal hood clearance. The TSP Vortec manifolds have additional provisions, including dual distributor hold-downs, 4-corner water ports, and a choke block-off kit. They are set up for spread bore carbs and include an adapter plate and gasket for use with square bore types. Note: As Vortec blocks do not have a water bypass, the manifolds are equipped with a provision to connect to a stock water pump using a 5/8 in. heater hose. Show Less
