SBF 351W Hi-Ram Intake 105MM EFI Black

The Holley SBF 351W Hi-Ram Intake 105MM EFI Black (SKU: HLY300-242BK) is a professional-grade tunnel ram intake manifold engineered for Small Block Ford 351W platforms seeking maximum airflow and EFI compatibility. Built for serious performance applications where intake efficiency directly translates to horsepower gains and throttle response, this manifold represents the modern evolution of classic high-rise intake design. Whether you're building a race engine, street performer, or high-output crate platform, the Hi-Ram architecture demands precision fuel delivery and optimized runner geometry—both of which this Holley unit delivers.

Constructed from cast aluminum and finished in durable black powder coat, the SBF 351W Hi-Ram features a 105mm EFI throttle body flange and includes integrated fuel rails, eliminating the need for secondary sourcing and custom fabrication. The tunnel ram design creates extended, tuned intake runners that enhance volumetric efficiency across the RPM band, while the EFI-ready architecture accommodates modern fuel injection systems for precise metering and real-world driveability. The manifold's vertical stack configuration maximizes underhood clearance in tight engine bays while maintaining the breathing advantages of dual-plane runner separation. At 40.95 lbs and measuring 27 inches tall, dimensional planning is critical for hood and accessory fitment.

This intake is purpose-built for 351W Small Block Ford engines and demands experienced installation; compatibility verification with your cylinder head port configuration and fuel injection controller is non-negotiable. Bracket engineering, vacuum line routing, and intake gasket sealing require methodical attention to prevent vacuum leaks and fuel delivery issues. Professional builders and experienced enthusiasts recognize that Hi-Ram intakes reward quality craftsmanship with repeatable, documented performance gains—making this Holley unit an investment in serious engine development rather than a bolt-on upgrade.
