Square Bore to Spread Bore Carburetor Adapter

Adapts a 4150 Square Bore Carburetor to a Stock Quadrajet or Thermo-Quad Manifold

0.850 in. Thick Cast Aluminum

Individual Venturi Port Design

Gasket Included

Sold as a Kit

Fitting a square bore carburetor to a factory Quadrajet or Thermo-Quad manifold means bridging two different bore layouts, not just a bolt pattern. This adapter uses individual venturi ports rather than one open hole, which preserves the separation between primary and secondary flow instead of dumping everything into a common plenum. At 0.850 in. thick, check hood clearance before committing.

Since founder Vic Edelbrock Sr. began building performance intake manifolds in 1938, Edelbrock has grown into one of the most trusted names in American high-performance parts, from carburetors and intake manifolds to cylinder heads, crate engines, and EFI systems. JEGS has spent decades supplying Edelbrock components to racers, engine builders, and street enthusiasts, backing this extensive lineup with in-house technical support, fast shipping, and a Price Match Guarantee so you can choose proven Edelbrock parts with confidence.

Carburetor adapters allow proper installation of carburetor to manifold.

Edelbrock Carburetor Adapters are precision-engineered solutions crafted to bridge mounting discrepancies between carburetors and intake manifolds. Ideal for performance enthusiasts seeking compatibility without compromise, these adapters allow you to retrofit a Holley-style carburetor onto an Edelbrock intake or similar setups—saving you from purchasing a completely new component.

Constructed from durable, lightweight aluminum, these adapters are built for longevity and ease of use. They're machined with exacting tolerances, ensuring a tight, seamless fit that maintains performance integrity while minimizing the risk of leaks.

Why You’ll Appreciate These Adapters

Cost-Effective Versatility: Whether you’re adapting a Holley carburetor to an Edelbrock manifold, or matching dissimilar intake and carb setups, this solution gives you flexibility without costly replacements.
Variety of Configurations: Choose the adapter that matches your specific application — from square-bore carb to spread-bore manifold transitions to side-mount options and more.
Simple Installation: Each kit typically includes necessary hardware and seals, simplifying installation. Keep in mind, though, that added thickness may affect hood clearance and introduces an extra surface that should be checked for vacuum-tight integrity.

Those searching for a reliable holley carb to edelbrock intake adapter will find these adapters to be a smart, practical choice. As an edelbrock carb adapter, it complements the brand’s commitment to performance and precision. And for anyone needing an edelbrock adapter plate, this component offers compatibility, craftsmanship, and peace of mind.

Upgrade your engine setup with precision-matched adaptability, confidently installing your preferred carburetor without compromise.
