Before it ever appeared on screen, “Maximus” was already one of the most ambitious Mopar builds anywhere — a 1968 Dodge Charger built by Tom Nelson of Nelson Racing Engines, discovered by a film crew at the SEMA trade show. Over 2,000 hours of bodywork and roughly 2,000 horsepower later, it closed out Fast & Furious 7 by recreating a scene from the franchise’s original 2001 film.
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.
This Model A wearing a flathead V8 is almost certainly a later hot rod swap, not a factory pairing — Ford’s real Model A ran a four-cylinder, and the V8 did not arrive until the 1932 Model 18. That original flathead made just 65 horsepower, yet Ford built over 3 million of them by 1936, launching the era’s most enduring engine-swap tradition.
This 1940 Ford Cabriolet’s spec sheet lists a 302 small block and C4 automatic, neither of which existed until decades after the car was built. See what Ford actually put under the hood back in 1940. Then see why swapping in a modern drivetrain has become the standard way to keep prewar Fords like this one on the road.
The 1965 Plymouth Fury III rode on an all-new full-size platform, and buyers could option it anywhere from a thrifty slant-six to a 365-horsepower Street Wedge V8 few ever actually ordered. Most Fury III buyers picked comfort over conquest, driving nearly 330,000 of these full-size Plymouths off dealer lots in a single year.
This 1966 Morgan Plus 4 still uses a wood-framed body and a Triumph-sourced four-cylinder engine, built the same way Morgan had built cars since 1950. It’s proof that hand-built simplicity found its own audience even during Detroit’s V8 arms race. Here’s the story behind Morgan’s stubbornly old-fashioned approach to performance.
Legend holds that Carroll Shelby trademarked the ‘King of the Road’ name in a hurry after hearing Chevrolet wanted it for a Corvette — securing it for his new 428 Cobra Jet-powered Mustang instead. Shelby built the GT500KR for barely two months in 1968, producing just 1,053 fastbacks and 517 convertibles — 1,570 cars total. Independent road tests of the era clocked it at 5.4 seconds to 60 mph, numbers that placed it among the quickest American cars you could buy.
The Jaguar XK120 began life as a one-off testbed for a new engine, but the reaction at its 1948 debut convinced Jaguar to build it — and the resulting car became the fastest production car in the world at the time. This 1952 example carries the original 3.4-liter inline-six good for 180 hp and a genuine 120-mph top speed. Jaguar built just over 12,000 XK120s between 1949 and 1954, with alloy-bodied cars now among the rarest of the breed.
The 1965 Skylark Gran Sport looked like just another well-dressed Buick, which made it one of the best sleepers of the muscle car era. Underneath the understated styling sat a 401-cubic-inch Nailhead V8 borrowed from Buick’s full-size Wildcat. Here’s how a luxury brand’s answer to the Pontiac GTO ended up hiding serious performance in plain sight.
Genuine 1933 Ford roadsters are scarce today largely because hot rodders spent decades cutting up the originals in pursuit of speed. That scarcity is exactly what fueled an entire replica industry, building accurate reproduction bodies around modern small-block V8 power. Here’s how the hot rod movement nearly wiped out the original 1933 Fords, and how replicas filled the gap.
The 1968 Camaro SS 396 could be ordered with three different versions of its big-block engine, ranging from a mild 325 horsepower to a genuinely quick 375-horsepower L78. Most buyers stuck with the base setup, which is exactly what makes the rarer combinations so collectible today. Here’s a breakdown of the engine options Chevrolet offered and how many of each actually made it out the factory door.
This 1964 Chevelle hardtop shows up in fresh red paint, aftermarket five-spoke wheels, and a white bucket-seat interior, clues that point to a full cosmetic restoration rather than a barn find. See what the photos can and cannot confirm about its original trim level, and why first-year Chevelles are drawing renewed attention from collectors today.
This 1934-style Ford coupe hides an outlandish build sheet: three Chevy 350 V8s, 24 exhaust pipes, 16 coats of Imron paint, and Bridge of Weir leather inside. See what the photos confirm about this triple-engine show piece, and why builds this extreme almost never make it past the fabrication stage.
This restored 1966 Chevelle SS looks period-correct on the outside, but its 565 cubic inch supercharged V8 making roughly 750 horsepower has nothing to do with the factory 396 options Chevrolet actually offered that year. Even the rarest original engine, the 375-horsepower L78, doesn’t come close. Here’s how this build compares to what left the factory floor.
