3/8" Holley 4-bbl Carburetor Spacers
Trans-Dapt Cast Aluminum Carburetor Spacers are one of the quickest and easiest ways to produce more power. By lengthening the intake plenum, these carburetor spacers increase volume by speeding up the flow of air and fuel that results in engine performance. Each carb spacer is CNC machined right here in the USA and is available in a variety of heights for use with Holley 2-bbl, and Holley, AFB and Quadrajet 4-bbl carburetors. All Trans-Dapt Cast Aluminum Carb Spacers come with the necessary gaskets and mounting hardware.Note: Not legal for use or sale in any state complying with California regulations.
Will this work with 850 speed demon carb and can i attach line from vacuum modulator to spacer tube?
Can I check manifold vacuum from this port and will it work with a 950 cfm Holley dominator carb?
