Chevrolet rushed its all-new Advance-Design trucks to market in mid-1947, beating every other Detroit manufacturer’s postwar redesign by roughly six months, and the formula worked so well the trucks stayed the sales leader every year through 1955. Here’s what changed under the skin of this 1948 example, from the column shifter to the standard heater.
Buick’s top 1966 Skylark performance option was the Gran Sport, built around a 401 cubic inch V8 nicknamed the Wildcat 445 after its 445 lb-ft torque rating, with horsepower ranging from 325 up to a hotter 340 horsepower version. Distinguished by blacked-out grille styling, GS badging, and heavy-duty suspension, a correctly documented Gran Sport survivor carries considerably more value today than a standard Skylark from the same year.
This 1974 Plymouth Duster 360 packs a de-tuned but still capable 360-cubic-inch V8 into a car built the same year Plymouth sold its Dusters primarily as fuel-conscious economy compacts. Plymouth built only 3,969 examples of this specific 360-equipped model, making it a genuine outlier in the Duster’s best-ever sales year. Here’s how Mopar squeezed real performance out of a car engineered for an oil crisis.
This 1923 Ford T-bucket pairs a 350ci small-block V8 with a body style that traces back to a 1950s Hollywood custom car and a TV show that introduced hot rodding to millions of viewers. Find out how a stripped-down Model T became one of the most copied shapes in American car culture, and why 1923 turned out to be the perfect year to build one from.
The 1967 Chevrolet Impala SS pictured here now runs a 350-cubic-inch V8 and two-speed Powerglide automatic — a later swap, since Chevy didn’t offer the 350 in a full-size car until 1969 — wrapped in Chevy’s freshly redesigned Coke-bottle bodywork. It also carries newly mandated safety features like an energy-absorbing steering column and front shoulder straps, arriving the same year Detroit was forced to start engineering for survival, not just speed. Here’s what made this particular model year such a turning point for the Impala nameplate.
The 1974 AMC Hornet Sportabout pictured here traded big-block horsepower for a fuel-sipping 258 CID inline six, arriving right as the oil crisis reshaped what American buyers wanted from a car. Built by the smallest of Detroit’s automakers, this wagon paired practicality with just enough flair to avoid feeling like a compromise. Preserved by Gateway Classic Cars, it survives today as a rare, honest example of AMC’s underdog engineering.
The 440 badge on this 1964 Dodge has nothing to do with the famous 440-cubic-inch V8, that engine did not exist yet. It was simply the name of a mid-tier full-size trim, sitting between the base 330 and the upscale Polara, standard with a modest 225-cubic-inch slant-six, V8 power only as an option. Paired here with Chrysler’s dependable 727 TorqueFlite automatic. Here’s how Dodge’s confusing 1964 naming actually worked.
Plymouth expected to sell about 20,000 Road Runners in 1968. It sold roughly 45,000, enough to land in third place behind only the GTO and Chevelle SS 396 for muscle car sales that year. The formula was simple: a standard 383-cubic-inch V8 rated at 335 horsepower, a stripped interior, and an optional 426 Hemi for those willing to pay more. It turned out buyers didn’t need luxury trim to want serious performance, they just needed the price to make sense.
The 1968 Camaro looks like a carryover at first glance, but small changes, new marker lights, vent-less door glass, a 396 big block for SS buyers, reveal how fast Chevrolet was reacting to the pony car wars. With 235,147 built that year, it was not just surviving its second season, it was gaining ground.
This 1986 Zimmer Quicksilver started life as an ordinary Pontiac Fiero GT before the factory cut it apart and stretched it into a neoclassic luxury coupe. Buyers paid nearly four times the Fiero’s price for the transformation, and only 170 were ever built. See what a former GM designer did with 29 inches of added sheet metal and a 140-horsepower V6.
Ford expected the new Mustang to sell 100,000 units in its first year — buyers blew past that mark in under three months. This gallery traces the first-generation Mustang from its record-breaking 1964 debut through the Boss 302 era, with a surprising twist: the launch year wasn’t even the Mustang’s best-selling one. See which model year actually topped the charts.
In 1970, Ford briefly revived the Falcon name as the base trim of its mid-size Torino line, and buried inside its options list was a 429 Cobra Jet that could be built to Super Cobra Jet spec. Only about 90 Falcons were ordered with that Drag Pack option, backed by a Detroit Locker rear and rated at 375 horsepower, and just 38 of those came with an automatic transmission. Produced for less than six months, the combination makes this one of the rarest big-block Fords most muscle car fans have never heard of.
The 1987 Corvette’s 5.7-liter L98 looks like a minor running change on paper, but it hid a valvetrain upgrade – roller hydraulic lifters – that did more for performance than the fuel injection system it’s usually credited for. Here’s how Chevrolet finally moved past its awkward Cross-Fire Injection years, and what quietly changed inside the engine that year.
This 1967 Buick Riviera arrived the year Buick retired its long-serving “Nailhead” V8 in favor of an all-new 430 cubic-inch engine making 360 horsepower and 475 lb-ft of torque. That swap dropped the Riviera’s 0-60 time to roughly 7.8 seconds, genuinely quick for a two-ton personal luxury coupe. Presented here through Gateway Classic Cars, it’s a well-documented example of the Riviera’s first year with its most memorable engine.
