Holley 4BBL Carburetor Spacer; Std. Manifold; 1-1/2 in. Tall; Open PlenumBillet

<p>It is no secret that tuners can alter their engine torque's sweet spot imply by increasing or decreasing the length plenum beneath the carburetor. It achieves this by increasing plenum volume and speed. To lengthen the plenum, simply install a carburetor spacer. For years, carb spacers have mainly been available in 1" or 2" tall varieties. This 4 barrel carb spacer measures 1-1/2" tall, and offers builders and drag aracers another level of tunability.</p><p>Hamburger's precision CNC machines this spacer in their Whittier, California manufacturing facilty using 6061-T6 aluminum, then giving a durable clear anoziding to protect it from the harsh engine bay elements. Hamburger's includes all the necessary gaskets and longer mounting hardware to accomodate the taller carburetor position. The spacer is designed with 8 mounting holes so it can be used with both Holley and AFB 4 bbl carburetors on a standard 4 barrel intake manifold. This particular model has an OPEN PLENUM design (no walls between the 4 carb ports), increasing the plenum volume even further, and is ideal for wide open throttle applications… like drag racing. This spacer is backed by a limited lifetime warranty!</P>
