In 1970, Oldsmobile produced what would be the ultimate iteration of the 442 model. In response to new regulations, the company made its mighty 455-cubic-inch V-8 standard. This gargantuan engine produced 365 horsepower and 500 pound-feet of torque, more than enough to take on competitors in the American muscle-car war. Checking off the “W-30” option on the build sheet brought even more power by adding a performance-calibrated, four-barrel carburetor, improved air induction, a hotter camshaft, and a low-restriction exhaust system. Total claimed output for the 442 W-30 was a heady 370 horsepower.
