If you’re looking to boost your Chevrolet V8's performance, the Edelbrock part #75621 RPM Air-Gap 2-R intake manifold is the perfect choice for street engines with 396-502 c.i.d. and high-performance rectangular-port heads. This intake manifold features an innovative design that includes an open air space, which effectively separates the runners from the hot engine oil. The result? A cooler air/fuel mixture that leads to a denser charge and, ultimately, more power.
This dual-plane, high-rise intake manifold has a 180-degree firing order that generates impressive top-end horsepower while still maintaining excellent throttle response. The larger plenum and runners are specifically crafted to complement free-flowing exhaust systems, high-lift cams, and other enhancements found in high-output engines. It's perfect for both street and competition setups that rev up to 6500 rpm.
You'll appreciate the thoughtful features included with this manifold, such as rear water outlets, two distributor clamp locations, and nitrous bosses. It’s designed to accommodate all late model alternator and A/C brackets, making installation a breeze. Please note that this manifold is intended for square-bore carbs only and does not include provisions for exhaust heated chokes or exhaust crossover.
Not only does this manifold perform well, but it also looks fantastic with its polished finish that adds a brilliant shine and classic touch to your engine bay. Upgrade your ride with the Edelbrock Polished RPM Air-Gap BBC Rect Port Intake Manifold and feel the difference!
