Ford’s 221-cubic-inch flathead V8 earned a nickname simply from its horsepower rating: enthusiasts still call it “the 85 horse” engine decades later, even though output actually varied across its production run. This restored 1938 Deluxe, shown here courtesy of Gateway Classic Cars, represents a quiet but important midpoint in that engine’s development, right before a bigger redesign arrived later that year.
1974 marked the final year Plymouth built the Road Runner on its original mid-size platform, with engine options still ranging from a mild 318 up to a 440 big block wearing GTX badges. Production had fallen to 11,555 cars, down from 19,056 the year before, as the muscle car era wound down. The Road Runner nameplate held on one more year on the larger Fury-based B-body before being reduced to a Volare trim package in 1976.
This 1969 Dodge Coronet Super Bee carries the rare A12 package, a 463-dollar option that swapped in a 440-cubic-inch V8 wearing three two-barrel carburetors for one strange mid-year run. Only 1,907 were built before Dodge moved on. Stock, these cars ran mid-13-second quarter miles, embarrassing plenty of pricier machinery on the strip.
This 1965 Corvette Sting Ray carries the standard 327 V8 and 4-speed manual, not the ultra-rare fuel-injected version Chevrolet also offered that year for $538. With only 771 fuelie cars built before the option quietly disappeared, most 1965 buyers picked exactly the setup shown here. It turned out to be the smarter choice for reasons Chevrolet is own big-block engine would soon prove.
This 1969 Plymouth Satellite carries a 383-cubic-inch Super Commando V8 that could be optioned up to 330 horsepower, serious muscle hiding under a car that never got the flashy Road Runner or GTX badging. Built on Chrysler B-body architecture alongside its more famous siblings, the Satellite offered the same underlying hardware with a lower profile. Sometimes the quiet option was the smart one.
Oldsmobile never built a 383-cubic-inch engine in 1971 – the factory topped out at 455 cubic inches for the 442, the last year it existed as its own model. This Cutlass instead runs a custom stroker build paired with a 4-speed automatic, restored on camera for the Car Warriors reality series. It’s a reminder that some of the most interesting muscle car builds are the ones that ignore the original spec sheet entirely.
Chevrolet’s 1965 Z16 option packed a 396-cubic-inch, 375-horsepower big-block into the Malibu SS body years before a proper big-block platform existed for it. The package included a heavy-duty chassis, reinforced frame, and a Muncie four-speed – no automatic was offered. At nearly 60 percent of a base Malibu’s price, the option itself scared off most buyers before scarcity ever entered the picture.
This 1956 Chevrolet Bel Air represents the middle year of the legendary tri-five run, powered by the 265 cubic-inch V8 that Chevrolet refined with an integral oil filter for ’56. Depending on carburetion, that engine ranged from a mild 162 horsepower up to a genuinely quick 240-horsepower dual-quad setup capable of a 16.3-second quarter mile. Chevrolet built nearly 700,000 Bel Airs that year alone.
Larry F. bought his first car in 1977 for $400: a white 1970 Pontiac GTO that broke his father’s one rule about first cars. He spent two years rebuilding it, drove it for years, and sold it in 1988 for $800 before the muscle car market took off. Years later, walking through an Illinois junkyard with his son, he found out exactly what became of it. Read on to find out what he saw.
Buick’s 1957 Roadmaster 75 wasn’t even a full-year model — it arrived mid-cycle in March, fully loaded, riding on a freshly enlarged 364-cubic-inch Nailhead V8. Only 12,250 were built, and just 28 remain registered with the Buick Club of America today. Here’s what made this mid-year Roadmaster stand out. Well-preserved survivors like this one are becoming exceptionally hard to find.
This 1948 Chevrolet sedan left the factory with a 216-cubic-inch six and a three-speed gearbox built for practicality. Decades later, someone dropped in a 454-cubic-inch V8 and a 4-speed, turning a postwar family car into a genuine sleeper. The transformation raises the obvious question: how much else got upgraded along the way?
Chevrolet’s brand-new 1966 Caprice was built for comfort, not speed — until you check the option sheet. Buried at the top sat the RPO L72, a 425-horsepower 427 big block that Chevrolet installed in just 1,856 full-size cars that year. This particular Caprice carries that rare combination under its luxury trim. It’s an odd, rare pairing that still turns heads wherever it shows up today.
The AC Cobra didn’t start out as the V8 icon everyone remembers — Carroll Shelby had to rip out its underpowered straight-six and drop in a Ford V8 to make the legend happen. Only 998 originals were ever built. This modern replica carries the same shape forward in carbon fiber over a tubular steel frame, shedding weight the original engineers never could.
A nineteenth-century French physicist’s glass jar of lead and acid still powers every muscle car on the road today. Gaston Plante’s 1859 lead-acid battery set the template that Delco and Detroit’s big-block engines would come to depend on for reliable starts. Here is how a decades-old invention quietly shaped the cars in this trivia list.
The 1966 Jaguar E-Type’s biggest upgrade wasn’t more horsepower, it was everything Jaguar fixed around the engine. A larger 4.2-liter inline six gained real mid-range torque, a fully synchronized gearbox erased the old car’s notoriously balky first gear, and a modernized electrical system made the E-Type as usable as it was beautiful. These photos, courtesy of Gateway Classic Cars, showcase a Series 1 example from the era widely considered the E-Type’s mechanical sweet spot.
