CNC machined from 1/2" 6061 billet aluminum, these 4V adaptors are used to install Holley and/or Autolite 4V square bore carburetors on our universal intake manifolds (sold above). The adaptor can be rotated, allowing the carb to be installed either perpendicular or parallel to the cylinder head. The holes used to mount the adaptor to the intake manifold, are drilled and counter sunk, allowing the use of Allen head cap screws (included), while the carb holes are drilled and tapped for standard 1/4" carb studs.


Intake manifold not included (sold separately).
