Intake Manifold Single Plain Race Manifold 298 302 347

This manifold is designed for racing or serious street applications using stock cast-iron or aftermarket Windsor style cylinder heads. Includes bosses that can be drilled and tapped for nitrous. It features a rear water crossover passage along with four corner tapped water ports. Ports are 1.90” x 1.08” at the gasket flange and the manifold contains enough material to open ports to 2.10” x 1.25”. Use Fel-Pro intake gasket #1250 or #1262. This manifold includes a 1/8-NPT vacuum port under the carb flange, a feature lacking in competitive manifolds of this type. Note that due to the port layout on small block Ford engines, a single plane manifold, such as this one, will typically be suitable for street use as long as the vehicle is not too heavy.
