The Performer Vortec is a dual-plane design that is tuned for maximum air flow from idle to 5500 rpm. Designed specifically for use on 1996-present Chevy 4.3L V6 Vortec engines in a marine application. One of the unique features is the brass lined water crossover and inserts to help protect the aluminum from salt-water corrosion and eliminate electrolysis in fresh water applications. It also features a carburetor flange that readily accepts square-bore and spread-bore carburetors. The Performer Vortec V6 Marine intake manifold is engineered to deliver maximum power and a broad torque curve for high-performance marine applications. Similar to the stock intake manifold, it includes a provision for 1/2 pipe water fittings on the front water crossover and 3/8 pipe horizontal vacuum fittings in the rear. Does not have a provision for an exhaust crossover, so an electric choke is required. Intended for marine use only and is not for street applications. Carburetor Recommendations: Edelbrock Marine Series carb 600 cfm and Q-Jets. Installation Notes: Recommended intake gasket: GM 89017866. Manifold Dimensions: A-3.60", B-4.44"; Carb pad height: 4.02", CA-3. Port exit dimensions: port exit is 2.05" tall with slanted side walls.

When you design and sell the best-engineered performance products in the world, you have to have a rigorous testing program. Why? Without adequate testing, there's no way to stand behind your product with confidence. That's why every product we design and sell at Edelbrock is tested and approved by Edelbrock engineers in a real world environment on state-of-the-art equipment. Our three Super Flow computerized engine dynos are capable of measuring 11 separate engine variables up to speeds of 12,000 rpm. For 2007, we added a new Super Flow SF902 engine dyno. It's fully automated and programmable to simulate various driving situations, and is equipped with WinDyn software for the very latest in testing equipment. For real-world tuning, there's our Super Flow model SF-840 eddy-current chassis dyno that can handle up to 1,000 hp at the wheels and speeds of 200 mph. When all testing is completed, the results evaluated, and the part has passed all performance criteria, then, and only then, is the product deemed ready for production. These precise testing procedures are applied to the entire Edelbrock line for performance that's guaranteed. Edelbrock test vehicles are driven by Edelbrock engineers and employees to get a "real world" feeling for the performance improvements. Our products are also tested and used by professional race car teams and drivers. Working with these talented individuals is just another extension of our research and development process so when we say "proven performance" we really mean it! Top racing teams in all forms of motorsports rely on Edelbrock to produce parts that they can count on to win races and championships. Further underscoring our commitment to the racing community, Edelbrock is the only aftermarket intake manifold manufacturer licensed by NASCAR.
