Edelbrock 8717 Carburetor Spacer 1 Inch Open Center for 4500 Series

The Edelbrock 8717 carburetor spacer is designed to increase plenum volume and improve air/fuel distribution in high-performance applications. This open-center design adds critical distance between the carburetor and intake manifold floor, helping to promote better atomization and mixture preparation.

Key Features:

• 1-inch thick open center design for maximum airflow
• CNC-machined aluminum construction for strength and heat dissipation
• Compatible with Holley 4500 Dominator series carburetors
• Works with Edelbrock Victor and Super Victor intake manifolds
• Open spacer design helps improve throttle response and power
• Precision-machined gasket surfaces for reliable sealing

Carburetor spacers like the 8717 are commonly used to optimize carb-to-manifold spacing on high-horsepower engines, particularly in racing applications where plenum volume and fuel distribution are critical to performance. The open center configuration allows unrestricted airflow while adding the benefits of increased plenum volume.
