Since the muscle car segment exploded in 1970 with big block power, some manufacturers offered smaller and nimbler alternatives to those 427, 455 or 454 engines. And one of those forgotten and obscure models is the Oldsmobile W31. You probably know about the Olds Rally 350 they made for 1970 only.
But this W31 was its twin with less “in your face” styling and similar power from the high revving 350 V8. The car featured lots of “go fast” options, too. However, it flew under the radar since most customers didn’t know it even existed. In the end, Oldsmobile produced just 116 of those interesting machines for the 1970 model year.
