66-67 Chevy II Outlaw Hood 4in Cowl

The 66-67 Chevy II Outlaw Hood 4in Cowl is a bolt-on performance air induction system designed for first-generation Chevrolet X-Body vehicles from 1966–1967. Built for enthusiasts seeking improved engine breathing and aggressive styling, this fiberglass cowl scoop transforms the hood's functional profile while maintaining OEM bolt-on compatibility. Cowl induction hoods work by capturing cooler, denser air from outside the engine bay and routing it directly to the carburetor intake, thereby enhancing volumetric efficiency and combustion consistency—a proven principle in street and strip performance.

This Harwood-engineered hood features a 4-inch tall cowl scoop constructed from durable fiberglass reinforced plastic, finished in black to complement factory and custom paint schemes alike. The 57.5-inch width and 65-inch length conform to original Chevy II body dimensions, ensuring proper fitment without modification to frame or structural mounting points. At 52 pounds, the fiberglass construction significantly reduces the weight penalty compared to factory steel hoods, improving weight distribution and handling characteristics. The scoop design allows atmospheric pressure recovery at highway speeds, which naturally increases intake charge density and supports reliable performance gains across the RPM band.

Restoration shops, hot rod builders, and Chevy II platform enthusiasts benefit most from this bolt-on upgrade, which installs using factory hood hinges and latches—no welding or permanent modification required. The design is compatible with both carburetor and early fuel-injection setups common to period-correct restorations and modern engine swaps. Installation takes approximately 30 minutes with basic hand tools. This hood complements upgraded intake manifolds, high-flow air filters, and cylinder head work, making it an essential aesthetic and functional component for serious X-Body performance builds.
