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 street 253-304-308 cid Holden V8. Fits Red/Blue/Black Motors. May have to drill out centre bolt holes depending on application. Will not fit EFI Heads. Made in USA
