Under the hood, a 400/350Hp powerplant was standard. While the total engine displacement may have been the same, Oldsmobile changes the bore and stroke to 3.87 x 4.25 inches. Compression was tight 10.5:1. The 442 could still be bought with the wild “force-Air Induction” package. This set-up gave you a 13 X 2-inch scoops mounted under the bumper directing air through to the single 4-barrel Rochester Quadrajet carburetor.

If money were no object, the W-30 package offers plastic inner fenders, a “blueprinted” engine, heavy-duty rear and cooling, cold-air induction, and a hi-performance camshaft. This engine was rated at 360Hp. In 1968 Oldsmobile offer something called a “junior supercar.” The W-31 Ram Rod package included a325Hp 350 cu.in. powerplant, a 3.91:1 rear, small port cylinder heads with oversized intake valves, a long duration camshaft that could wind up to 6000 RPM offering great street chops at a true barging-basement price.
