Ford Racing 351 NASCAR Restrictor Plate Intake Manifold

Ford Racing's 351 NASCAR Restrictor Plate Intake Manifold line is purpose-built, factory-backed hardware engineered for serious oval track competition. Developed to meet NASCAR restrictor plate rules and CFM-controlled carburetor class regulations, these manifolds carry decades of Ford motorsport expertise in a race-ready package — manufactured in the United States to the same exacting standards as Ford's factory NASCAR programs.

Key Features:

• Single-Plane Spider-Type Design: Lightweight single-plane architecture optimized for maximum airflow efficiency under restrictor plate and controlled carburetor class conditions, from superspeedways to short tracks
• Lightweight Aluminum Construction: Cast aluminum keeps overall engine weight to a minimum while delivering the structural integrity required under sustained race conditions
• Yates-Style Cylinder Head Compatibility: Engineered for use with Yates-style and compatible cylinder heads on tall-deck 351 race blocks, enabling seamless integration into a NASCAR-specification engine build
• Elevated Carburetor Pad: Raised carburetor pad positioning supports optimal fuel delivery and airflow performance throughout the RPM range
• Extra Runner Wall Thickness: Generous material on runners allows further custom porting and modifications to suit individual engine builder specifications
• No Valley Tray Included: Valley tray is intentionally omitted for maximum weight reduction; a separate lifter valley cover plate is required for installation
• USA Manufactured: Produced in the United States to the standards of Ford's factory NASCAR racing programs
• Multiple Configurations Available: The product line spans a range of deck heights, carburetor pad heights, and cylinder head combinations to address various NASCAR rulebook specifications and class requirements

Each variant in this line is engineered to a specific combination of deck height, cylinder head type, and carburetor pad height. Always confirm the correct configuration for your cylinder head, block deck height, and sanctioning body rulebook before ordering. A lifter valley cover plate is required for installation and is not included. Sold individually.
