22. Oldsmobile 442 W30
Olds introduced the 442 in 1964, and it got a mild refresh for the 1966 model year and five HP more. And that meant the 400 V8 now produced 350 HP. This rating placed the Oldsmobile among the most powerful of Detroit muscle cars at the moment. But the most interesting model was the W30.
If you opted for that, you got a special ram air induction system with tubes going from the front bumper to the carburetors. Also, the W30 had a hotter cam and a few other go-fast options. Being a little conservative, Oldsmobile didn’t put any wild graphics or emblems on the car. So the W-30, which was significantly faster than the regular model, looked the same. Even though the price of the W-30 package wasn’t high, people somehow overlooked this model, so they only made 54 of them. This is a small percentage from the over 20,000 442s they built for the 1966 model year.
