    Manufacturer's Part Number:

    Holley carburetor spacers are available in cast aluminum or phenolic. Whether your raising the carburetor due to clearance issues or simply want a little more space between the carburetor and intake manifold, Holley has the spacer for you.
    Wedge Plates allow the carburetor to sit level on tilted engines (typically marine applications).

    108-37 - Holley Carburetor Spacers is rated 2.0 out of 5 by 1.
    Rated 2 out of 5 by from It Fit, but took awhile to make it fit I just installed a q-jet carb on my 396, and had a fuel boiling issue. After some research, I decided to go with one of these spacers. The first time I installed it in about 10min... Took the car out, it seemed very sluggish. With a closer look, I found the secondaries wouldn't open because the holes in the spacer we're misaligned. Took the spacer out and spent another 40 min or so enlarging the holes. In the end, it runs better, and slightly improved the boiling fuel.
