A GM policy decision banning multiple carburetors for all vehicles except Ed Cole's beloved Corvette and the Corvair saw the demise of the L69 with its triple carburetors, a rare option for Olds and an icon for Pontiacs since 1957. The W30 remained available, although the four-barrel Quadrajet carburetor replaced the tri carb setup. New red plastic inner fender liners became part of the W30 package. 502 factory W30 engines were built to meet NHRA homologation rules, along with an unknown number of dealer-installed packages.
