1970 Oldsmobile 442 W-30 Convertible

Vying to compete with Pontiac’s GTO, the honchos at Oldsmobile ginned up this 442 option, derived from the “police apprehender” version of its Cutlass. The beefed-up beauty has a four-barrel carb, four-speed manual, a dual-plate clutch, and a 455 cubic-inch V-8 making 370 hp.

The W30 package tacked on extra speed and efficiency bits, including a functional air scoop on the hood, an aluminum intake manifold, and an upgraded cam. A total of 3,100 examples of the 442 were built, but only 264 of them were convertibles.
