Chevrolet may have been late to the 8-cylinder engine, but once it got there, it did so in a big and long-lasting way
Editor’s note: This is part two of a five-part series looking at the history and future of the muscle car. Read the whole series during July, when the ClassicCars.com Journal celebrates all things muscle.
Although Chevrolet had a V8 in vehicles way back in 1917 and 1918, it abandoned that architecture, and even skipped the straight-8 setup used by other General Motors divisions. It wasn’t until the 1955 model year that Chevrolet launched its own V8, called the Turbo-Fire engine.
At first, that engine displaced 265 cubic inches and powered the Bel Air sedan (with 162 horsepower) and the Corvette roadster (with 195 hp). But through the years, the engine would prove to be transformational among automotive powerplants and would emerge as the basis for Chevrolet (and GM) V8s for decades to come.
It worked for hot rodders as well. Look into the engine bay of many hot rods and custom cars for various brands and you’re liable to see a tried-and-true small-block Chevy V8.
Once it got into the V8 business, Chevrolet realized it needed even more power, primarily for trucks but also for larger passenger cars, so for the 1959 model year, it rolled out a big-block V8. The first version displaced 348cid, but for 1961 displacement grew to 409, and in 1962 to 427.
Even if you care nothing about cars, that 409 figure should ring a bell because it not only ignited a second round of muscular machines from Detroit, but a popular hit song by The Beach Boys:
“Well, I saved my pennies and I saved my dimes
(Giddyup, giddyup, 4-0-9)
For I knew there would be a time
(Giddyup, giddyup, 4-0-9)
When I would buy a brand new 4-0-9.”
Chevrolet’s full-size sedan, the Impala, could be equipped with the 409 engine, and with a dealer-installed Super Sport trim package that included SS emblems, power brakes and steering, heavy-duty springs and shocks, a 7,000-rpm tachometer and narrow-band white-sidewall tires and special wheel covers.
The 409 engine provided 360 horsepower, enough to power the Impala 60 mph in less than 7 seconds and down the quarter mile in 15.8. Stuffed into a lighter Bel Air coupe, the 409 won the national Top Stock Eliminator drag-racing championship.
The early-to-mid 1960s were the era of factory-backed, production-based stock-car and drag-racing programs, the latter part of the Super Stock or A/FX (Factory eXperimental) category.
Ford, in its Total Performance heyday, produced lightweight Galaxies with 406cid V8s and later, lightweight Fairlane Thunderbolts powered by 427cid engines for drag racing. There also were tricked-out Mercury Comets.
Pontiac had its Catalina Super Duty with a 421cid V8 pumping out more than 400 horsepower. There was a Plymouth Sport Fury with a big Hemi V8 for the street, and Dodge had the Coronet A990 and Plymouth, its much-altered Belvedere with a 426 Hemi V8 for drag racing.
As more and more modifications were made to the production-based cars, a new professional racing category — purpose-built Funny Cars, basically Top Fuel racers disguised with fiberglass stock-style bodies — would emerge.
And before too long, Detroit would turn its attention from the track and strip to putting more power on the street.6 comments
