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.

The badge on this car says V8, but the Lincoln-Zephyr that defined the late 1930s never came with one from the factory — it ran a smooth, compact V12 unlike anything else in Lincoln’s lineup before or since. Edsel Ford personally championed the design, and it helped save Lincoln during the Depression. Here’s the real story behind the engine that made the Zephyr famous, and what a V8 badge on this example likely means.

The Chevrolet El Camino SS Choo Choo package earned its odd nickname somewhere along the way, and by 1987, the very last year Chevrolet built an El Camino at all, buyers had one final chance to check that option box. Only 861 of these were built in that final model year, out of roughly 4,950 total across the package’s entire run. Here is what made this quirky appearance package a genuine send-off for one of Chevrolet’s most unusual nameplates.

1967 marked the final year of the Chevrolet El Camino’s second generation, and one of its most overlooked performance years. Buyers could order this car-truck hybrid with seven different powertrains, topping out with an SS396 big-block borrowed straight from the Chevelle. With just 34,830 built, clean surviving examples of this last-of-its-kind El Camino are increasingly hard to find.

Most 1958 Pontiac Star Chiefs left the factory with a 370-cubic-inch V-8, but a rare Tri-Power option pushed output to 300 hp — with an even rarer fuel-injected version topping 310. Sales that year collapsed by roughly 60 percent for Pontiac, making surviving examples scarcer than the model’s reputation suggests. This particular car pushes well past its factory roots with a big-block swap, turning a once-overlooked flagship into a genuine hot rod.

By 1974, Plymouth had swapped the beloved 340 out of the Duster for a detuned 360 that made noticeably less impact despite the larger displacement. Yet against all odds, 1974 became the Dusters best sales year ever, with 281,378 cars produced during the height of the first oil crisis. Fewer than 4,000 of those were the new 360-powered version. What does a sales record set under the worst possible conditions say about what buyers actually wanted?

A six-cylinder Malibu that’s been in the same hands for nineteen years doesn’t get to 520 horsepower overnight. Jeffery’s slow-build street rod — big-block swap, upgraded rear end, reworked suspension — is a reminder that the best builds in this community are usually years in the making, one system at a time.

This 1969 Dodge Coronet R/T convertible carries the standard 375-horsepower 440 Magnum, but the same order sheet hid a far rarer option that almost nobody chose. Only 97 hardtops and 10 convertibles left the factory with the fearsome 426 Hemi that year. Find out why the Coronet R/T’s popularity was already fading fast by the time this car was built.

Chevrolet built its last El Camino in 1987, and by most counts it was also the rarest single year of the model’s entire run — barely over 13,000 built, including fewer than 900 SS models. Buyers were down to just two engines, a base V6 or an optional 305 cubic-inch V8, with the manual transmission long gone from the order sheet. There was never an official send-off; production simply wound down quietly at Chevrolet’s Mexico plant. Here’s the real story behind the final year, and why the persistent “1988 El Camino” rumor doesn’t quite hold up.

Packard built roughly 55 examples of the 1603 Super Eight Touring Sedan for 1938, and today only about two dozen are believed to survive. It was the lightest body style in the whole Super Eight lineup, which meant it was also the quickest, riding on a 320 cubic inch straight-eight and a shorter 127-inch wheelbase. This Gateway Classic gallery captures a genuinely scarce piece of Depression-era engineering most people would drive right past without a second look.

This 1970 Chevrolet Chevelle SS traveled from Georgia to Florida to an Indianapolis museum before landing on Vanguard Motor Sales’ lot with its original factory build sheet still intact. Under the hood, the numbers-matching 396 has barely turned over since a 1999 restoration. It’s the kind of paper trail that usually gets lost decades before a car like this survives to tell its own story. Watch to see what else has stayed frozen in time.

A 1971 Ford Torino sitting on Gateway Classic Cars’ lot might not wear a Cobra Jet badge, but its 302 V8 and Cruise-O-Matic transmission tell a different kind of muscle car story — one about the last year before emissions rules and insurance premiums reshaped Detroit’s mid-size performance cars for good. With only 31,641 GT-trim Torinos built for 1971, and just over 3,000 Cobra hardtops among them, even the “everyday” Torino V8s are becoming harder to find in this kind of condition.

Gateway Classic Cars is showing off this 1966 Ford Thunderbird, built the year Ford quietly reworked the 390’s heads and carburetor for smoother power. Buyers that year overwhelmingly chose the vinyl-roofed Landau over the convertible, making today’s survivors an interesting split of common and genuinely scarce. See the full photo set and find out what made this the last great pre-’67 Thunderbird.

The 1967 Plymouth Belvedere lived a double life — one version chased down traffic violators for the LAPD and starred in Adam-12s pilot episode, while another, ordered with the rare 425 horsepower 426 Hemi option, could out-muscle nearly everything else on the road. Only 720 buyers checked that Hemi box that year, making it one of the most overlooked factory Hemi cars Mopar ever built.
