Chevy V6 Marine Intake
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.

Specifications:
I have the 262 cu in v-6 vortex heads marine 4.3 engine. Was looking for a Holley carb to put on this manifold. Looks like Holley # 80364 might be the appropriate carb. This engine breathes around 400 cfm’s. Good match ?
