SBC Intake Manifold RPM Marine 1987-1995

The SBC Intake Manifold RPM Marine 1987-1995 by Edelbrock represents a purpose-built performance upgrade for small-block Chevrolet marine engines operating in that model year window. This aluminum intake manifold addresses a critical gap in marine powerplant design: factory intake runners constrain airflow and limit cylinder charging efficiency, directly reducing horsepower and throttle response in high-demand boating applications. Whether you're rebuilding a tired 350 or maximizing output on a 327, the RPM Marine design delivers measurable gains in both peak power and mid-range torque where marine operators need it most.

The RPM Marine intake features Edelbrock's signature dual-plane runner geometry optimized for marine duty, which distributes charge evenly across all eight cylinders while minimizing reversion losses during gear transitions and throttle modulation. The design incorporates a marine-specific carburetor flange and water passage routing that integrates seamlessly with factory cooling systems, eliminating the need for aftermarket thermostat housings or bypass modifications. At 20.73 lbs, the aluminum construction saves significant weight compared to iron factory manifolds, reducing overall engine mass and improving boat handling characteristics. The manifold's compact envelope (11.4 × 5.75 × 21.75 inches) ensures clearance in typical marine engine compartments without requiring custom fabrication of intake plumbing or air cleaner assemblies.

Marine mechanics and serious hobbyists restoring 1987–1995 SBC-powered vessels will find the RPM Marine manifold indispensable for addressing stock flow restrictions without complete induction system redesign. The intake bolts directly to existing cylinder heads using factory fastener patterns, making installation straightforward for anyone with basic mechanical competency and a torque wrench. Compatibility extends across all small-block variants in this era, including 305, 327, and 350 displacements, making it a smart choice for mixed-fleet maintenance or progressive engine modifications. Pair this manifold with a quality carb spacer and matching fuel delivery system to unlock the full potential of your marine powerplant.
