Edelbrock part #28001 Big Victor 2 Spread-Port intake manifold is designed for large cubic-inch or high rpm drag racing big-blocks with Edelbrock Big Victor, Dart Big Chief or Brodix Big Duke cylinder heads, this manifold has an average runner area of approximately 4.75 sq. in. The port exits have been reduced to accommodate the wide variety of intake port sizes and require port matching. The runners have a minimum corner radius of .500" from the plenum to the exit allowing the popular oval port shape to be used. The outside runners are shorter and straighter than competitor's manifolds and the plenum is longer front to back. These features, combined with approximately 5% taper in runner cross-sectional area, give better top end horsepower while maintaining consistency and throttle response off the stop. All applications are equipped with a 4500 Series flange and will accept 2.25" throttle body butterflies without a spacer or modification.
