Carburetor Spacer Adapter Conversion 455 Buick Edelbrock B4B Intake to Holley Stage2

Back by popular demand is our custom CNC Machined 6061 Billet Aluminum carburetor spacer adapter to convert your Edelbrock B4B spread bore intake manifold to accept a Holley 4150 style carburetor.

What makes this spacer truly unique is that we laser scanned both Edelbrock B4B intake manifolds spread bore and square bore designs and married the two to come-up with a piece that looks like is was designed for your engine. We also designed these such that you could mill down your Edelbrock Spread-Bore B4B and actually weld this spacer directly to the B4B spread bore intake manifold to truly convert to a square bore intake. 

We have added a new graphic and polished the graphic area to clearly reveal the custom designed logo. 

Note: Carburetors and intake manifolds shown in the photos are not included.
