CLASSIC OLDSMOBILE W-31 Option

  • By: Lisa Thornton

The W-31, is a cold-air kit on a high-performance 350-cid V-8, installed in an F-85 Cutlass, clamped over a 442 suspension.  The W-31 is quite a car.

The engine gets the full treatment. Higher compression, new cylinder heads with big valves, streamlined exhaust manifolds, a big four-barrel carburetor fed by scoops under the bumpers, and a wild camshaft.  The factory rates the engine at 325 bhp.

The engineers built a smaller Turbo Hydro-Matic matched to the W-31 engine.
