Performer or Victor Jr. manifolds are allowed for the 2011 racing season.
PERFORMER� MANIFOLDS (Idle to 5500 rpm)
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 domestic V8 and some V6 engines. Most Performer intakes are 50-state street legal, when used with the correct carburetor and in the correct application. Check the individual listings for detailed information.
Chevrolet 262-400 Small-Block V8
VICTOR JR. (3500-8000 rpm)
These versatile manifolds are excellent for many applications from high-performance street to drag/circle track racing. They provide maximum performance for engines with standard port location, iron and aluminum cylinder heads. The low-profile of the #2975 works well in applications with minimal hood clearance and where 1" or 2" spacers can be used for performance tuning. When carb spacers are not allowed, the #2999 should be used. The Victor Jr. Port Matched manifold has CNC-blended port exits that match any competition head using Fel-Pro gasket #1205.
