The Edelbrock Performer #21763 intake manifold is designed for street 318-340-360 c.i.d. Chrysler V8's. This manifold is not for use on marine engines used in salt water. Will not fit 1992 and later Magnum engines. Performer manifolds are dual-plane, low-rise intake manifolds with a 180? firing order and patented runner design that you won't find in other brands. This patented design greatly improves torque over a wide rpm range for excellent throttle response, especially off-idle through the mid-range. The Edelbrock Performer # 21763 intake manifold is ideal for passenger cars, trucks, 4x4s, tow vehicles and RVs. The Edelbrock Performer #21763 also features a durable black powder coated finish for long lasting protection and a distinctive look. For the ultimate "Made in USA" quality, every Edelbrock intake manifold is cast and machined in the USA.
