BIG VICTOR SPREAD-PORT (3500-8500 RPM) 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, these manifolds have an average runner area of approximately 4.75 sq. in. The port exits have .090" per side reduction 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. Big Victor High-Rise intake manifolds are based on our popular Big Victor designs, but have been modified to meet the needs of custom porting specialists. The casting has added material on the top of the runner and exterior area of the carb pad. This gives engine builders the extra material they need to apply custom porting without welding. Big Victor 2 intake manifolds go one step further. They have the same outer dimensions as the Big Victor High-Rise, but also have an extended runner design, carb pad and plenum for increased air flow and performance in large displacement race engines. These intake manifolds are designed to perform right out-of-the-box with minimum modifications, but can still be ported as needed. Port matching is required for best results. All applications are equipped with a 4500 Series flange and will accept 2.25" throttle body butterflies without a spacer or modification.
