SBC Performer RPM Manifold - 262-400

The SBC Performer RPM Manifold - 262-400 by Edelbrock is a high-performance intake manifold engineered for small-block Chevy engines ranging from 262 to 400 cubic inches. Built for enthusiasts who demand responsive throttle characteristics and improved mid-range torque, this manifold bridges the gap between bolt-on affordability and racing-grade performance. Whether you're upgrading a street machine, weekend cruiser, or mild performance build, the Performer RPM delivers repeatable gains without requiring major engine modifications or fuel system overhauls.

The manifold features carefully optimized runner geometry that promotes efficient air and fuel mixture distribution across all eight cylinders, reducing fuel pooling and combustion irregularities that plague stock designs. Cast from premium aluminum alloy, the Edelbrock design incorporates a low-rise profile that maintains excellent hood clearance while maximizing plenum volume for enhanced volumetric efficiency in the 1500–6500 RPM band. The dual-plane runner configuration isolates alternating cylinder pairs, allowing smoother power delivery and better throttle response compared to traditional single-plane designs—a critical advantage on naturally aspirated engines where every cubic foot of air flow matters.

This manifold is ideal for small-block Chevy owners running carbureted or electronic fuel injection systems who want reliable power gains without exotic cam timing or radical compression ratios. Installation is straightforward on any stock or modified 262–400 SBC block with factory bolt patterns, and it accepts standard Chevy intake gaskets and carburetor adapters. At 18.17 lbs, the aluminum construction reduces overall engine weight compared to cast-iron stock manifolds, contributing to improved handling dynamics on street and strip applications. Pair it with a quality carburetor tuning or EFI calibration for optimal results.
