By 1951, Cadillac’s Series 62 wasn’t just popular — it accounted for nearly three-quarters of everything the brand sold that year. A dependable new overhead-valve V8 and a lineup of trim levels ranging from a plain sedan to the chrome-heavy Coupe de Ville gave postwar buyers a reason to finally trust Cadillac’s V8 over the flathead engines that came before it.
The 1949 Oldsmobile 98 Holiday paired a landmark body style, one of the first hardtop coupes GM ever built, with only 3,006 produced, with an engine that changed the industry outright: the 303-cubic-inch Rocket V-8, the first mass-produced overhead-valve V-8 in America. Together they cut 10-to-60 mph times by 4.6 seconds over the prior year’s car and helped kick off the horsepower race that would define American muscle cars for decades to come.
Chevrolet built only about 80 examples of the race-bred RPO L88 Corvette in 1968, stripping out the radio and heater in favor of aluminum heads, a solid-lifter cam, and brakes borrowed from the competition parts bin. This coupe from the Brothers Collection is one of the rarest, most authenticated survivors of that run, and V8TV’s cameras get an up-close look at exactly what made it different from every other 427 Corvette that year.
For two straight seasons Carroll Shelby’s 427 Cobra had been embarrassing Corvettes, and by 1966 Chevrolet had run out of patience. The answer was to fit a 427 cubic inch big block into the C2 Sting Ray for the first time, offered in two very different states of tune. One was a strong street engine. The other was a solid lifter, eleven to one compression monster that almost nobody believes was honestly rated, and only 5,258 buyers took it.
