The 1966 Chevrolet Nova SS started life as a humble compact, but buried deep in its order form was an engine option that turned it into one of the quickest bargains on the street. For 2,535 dollars, the right box checked could put a genuine performance engine under the hood of a car most people assumed was just economical transportation.
The 1978 Buick Riviera looks like a routine luxury coupe, but it was actually a stopgap built to bridge two very different eras of Buick design. Hidden inside that final model year was a low key 75th anniversary edition almost nobody remembers, plus an optional Oldsmobile built V8 that changed the car’s whole personality.
By 1973, insurance surcharges, emissions rules, and new bumper regulations had already reshaped the muscle car era that once defined Plymouth’s Barracuda. The E-body soldiered on regardless, sharing its platform with the Dodge Challenger. Production numbers from this final full season tell a quieter, less celebrated story than the Hemi-powered years that usually get the attention.
Ford never marketed the Thunderbird as a sports car, even though it arrived the same year Chevrolet was building the Corvette into exactly that. Instead, Ford created the personal luxury car segment, and 1956 brought a handful of small but meaningful fixes to the original formula. Just 15,631 were built that year, making it the rarest of the three original two-seat Thunderbirds.
This Ford Model T “Lightning Bug” was driven by “Kookie” on the late-1950s TV hit “77 Sunset Strip,” spawning countless look-alikes over the decades since. Reportedly the genuine article rather than a replica, it now wears a 454-cubic-inch big-block Chevy engine in a body built for basic 1920s transportation. Here is how that unlikely combination came together.
Chevrolet officially rated the 1967 Corvette L88 at 430 horsepower — a number almost nobody believes, with real output reputed to be closer to 560 or even 600. Only 20 of the 22,940 Corvettes built that year carried the option, which required deleting the heater, radio, and air conditioning just to qualify. A Sunray DX-entered L88 went on to win the 12 Hours of Sebring outright that same year. Read on for how Chevrolet built the most powerful — and most deliberately hidden — engine it ever put under a Corvette hood.
The Oldsmobile 88 nameplate traces back to 1949, when it paired a lightweight body with the division’s new Rocket V8 — a combination some historians credit as one of the earliest true muscle cars. By 1975, the Delta 88 had grown into a full-size comfort cruiser facing new emissions rules, yet it quietly offered one of the first production airbag options in America.
The redesigned 1971 Dodge Charger arrived with all-new fuselage styling and one of the last truly serious muscle-car engine lineups before insurance costs and gas prices closed the era down. Buyers could still order a 440 Magnum, a 440 Six Pack, or the legendary 426 Hemi – though only 63 R/T Chargers left the factory with that Hemi. Here’s the story behind these images and the numbers that made this the end of an era.
The 1967 Coronet R/T was Dodge’s first R/T-badged car, and there was no watered-down version to choose from, buyers picked between a 375-horsepower 440 Magnum standard or the legendary 426 Hemi as the sole upgrade. Just over 10,000 were built in that debut year, most of them two-door hardtops, setting the template Dodge would use across its R/T lineup for years to come.
Chevrolet rated the 1970 Chevelle SS 454’s LS6 engine at 450 horsepower, but nobody who dyno-tested one believed the number — Super Chevy Magazine’s own testing pointed to something closer to 500. It was the most powerful engine Chevrolet ever put in a Chevelle, offered for exactly one year before EPA rules ended the experiment. Only 4,475 LS6 Chevelles were built in 1970, and just 137 are verified on today’s national registry. Read on for what made this one-year-only big block so different from every 454 that came after it.
The 1971 Hemi Cuda is the rarest and most valuable regular-production muscle car America ever built, and the reason is straightforward arithmetic: 108 hardtops and 11 convertibles left the factory, and then the option disappeared forever. It was also the only year the Cuda wore four headlights and fender gills. One convertible has sold for $3.5 million. Read on for what happened in that single model year.
Ford built the FE 427 Cammer to solve one problem: Chrysler’s 426 Hemi was dominating NASCAR, and a conventional block wasn’t going to catch it. The side-oiler engine replaced a normal camshaft with an idler shaft and a six-foot timing chain driving twin overhead cams, hollow sodium-filled exhaust valves, and a hemispherical combustion chamber Ford couldn’t even call a Hemi because Chrysler owned the name. Sold as a crate engine in 1968, the dual-carb version made 657 horsepower for $2,350. Read on for how Ford’s FE family evolved from Mercury’s 410 to this NASCAR-killer.
Pontiac’s 1956 Star Chief is best known today for its Silver Streak trim and flagship status, but buried mid-year was a rare 285-horsepower dual-four-barrel engine option most buyers never ordered. The standard V8 already delivered 216 to 227 horsepower depending on transmission, good for a 0-to-60 run under 12 seconds. Pontiac still built over 127,000 Star Chiefs that year despite its premium positioning. Here’s the full engine story behind these images.
A Hennessey HPE650 Camaro, a Shelby Super Snake, and a SpeedFactory-built Challenger SRT8 lined up with one thing in common: none of them left the factory anywhere close to this powerful. Hennessey went the naturally aspirated route with ported heads and cams, Shelby went straight to a Whipple blower, and SpeedFactory brought the Mopar. Here is why weight and traction usually decide these matchups long before horsepower does, and why the format of the race changes the answer.
