SBC Performer Air Gap Manifold - 262-400

The Edelbrock SBC Performer Air Gap Manifold (Part #2601) is a dual-plane aluminum intake manifold engineered for small block Chevrolet engines in the 262–400 cubic inch range. The air gap design creates a thermal barrier between the intake runners and the engine block, reducing heat transfer to the incoming fuel charge and promoting denser, cooler air for improved combustion efficiency and power output across the RPM band.

This manifold features a spread bore carburetor mounting pattern compatible with square bore carburetors, making it adaptable to both stock and modified fuel delivery systems. The dual-plane runner design balances low-end torque with mid-range response, delivering predictable power characteristics without excessive idle vacuum or cross-ram effects. The natural aluminum finish resists corrosion and simplifies maintenance, while the 16.4-pound weight keeps parasitic mass in check. The manifold's compact footprint (11.3 × 21.7 inches) fits within standard engine bay clearances on most small block Chevy platforms.

Builders and engine tuners select the Performer Air Gap for naturally aspirated small block applications where improved charge density and thermal management translate to measurable gains in horsepower and torque. Whether assembling a street engine, a weekend cruiser, or a performance build, this manifold serves as a foundation for reliable, repeatable power delivery without exotic tuning requirements.

Edelbrock's Performer line remains the industry benchmark for intake manifold design, delivering documented performance improvements over stock configurations at a competitive price point. This manifold represents the balance between peak performance and practical durability that serious engine builders expect.
