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. Performers are ideal for passenger cars, trucks, 4x4s, tow vehicles and RVs. There are EGR and non-EGR versions available for most V8 and some V6 engines.

• Designed for 351M-400 Fords in one of the three following configurations: 1) OEM 2V carb and EGR system with supplied 2V EGR spacer; 2) 4V EGR system with either an Edelbrock # ED8053 4V EGR spacer, or an Edelbrock # ED8017 and Ford # E4ZZ9A-589E 4V EGR spacer; 3) For off-highway use, non-EGR 4V system with an Edelbrock # ED8714 adapter.
