- Major notes about these manifolds
- For MerCarb Carburetors (identified by single adjustment screw & 3.69" x 2.00" mounting stud pattern & single idle adjustment screw at the base)
- This style of manifold had the mounting bosses for shift component hardware found on earlier style 4cyl engines that Shift bracket mounting to the side manifold vs. built into the rocker cover (1990 & up)
- This item has been cleaned & repainted and is ready to be installed.
- This manifold was used on basically all 3.0L 140hp 4-Cylinder engines WITH Mercarb carburetors
- Since this does have the mounting bosses (threaded holes for the throttle linkage) this is universally compatible with all of the 120hp / 140hp models using MerCarb carburetors with top or side mount throttle control.
