Chevrolet Special Deluxe 350 CID 1940 images

A 1940 Chevrolet badge and a “350 CID V8” listing title should not belong to the same car, and yet here they are. This piece looks at what actually rolled off the factory line in 1940 (an 85-horsepower straight-six, not a big-block V8) and how a car like this ends up with a completely different heart decades later.

The badge on the deck lid still says 1940. The listing title says “350 CID V8.” Neither one is lying, and that contradiction is exactly what makes this particular Special Deluxe worth a second look. Chevrolet’s original 1940 lineup never came within a mile of a 350-cubic-inch V8 — this car left the factory with something far gentler under the hood, built for cruising, not launching. Somewhere between the factory floor in 1940 and the photos Gateway Classic Cars shared here, this car picked up a very different heart. So what actually changed?

What Actually Left the Factory in 1940

The real 1940 Special Deluxe ran an overhead-valve inline six displacing 216.5 cubic inches, fed by a single Carter one-barrel carburetor, rated at 85 horsepower at 3,400 rpm and backed by a three-speed manual with a column shift. Marketed under the slogan “Royal Clipper Styling,” the car wore flowing lines, an “alligator” hood, and a grille that borrowed heavily from Chevrolet’s pricier sibling, Buick. It worked: Special Deluxe production reached 430,945 units for the model year, more than 55 percent of everything Chevrolet built in 1940, offered across coupe, convertible, sport sedan, wagon, and town sedan body styles.

A V8 That Came Along Decades Later

The “350 CID V8” referenced in this listing points to a well-worn restomod path for prewar Chevrolets: swapping in a small-block Chevy 350, an engine design that wouldn’t exist for another fifteen-plus years after this car left the assembly line. The trade keeps the original Silver-era sheet metal and cabin intact while delivering modern reliability and power the factory six was never built to produce — which is likely exactly what’s sitting under the hood in these Gateway Classic Cars photos.

The Color In These Photos

These Gateway Classic Cars photos show a deep green metallic convertible, not the orange sometimes used to describe similar listings, paired with a cream or tan interior, whitewall tires, and ornate chrome bumpers and taillight bezels typical of Chevrolet’s 1940 flagship trim. The top-down presentation and rounded fastback-style trunk give the car a graceful, formal profile that reflects its position at the top of Chevrolet’s 1940 lineup.

A Body Style Built For Comfort, Not Speed

The Special Deluxe convertible sat at the top of Chevrolet’s 1940 range, above the base Master 85 and standard Deluxe lines, aimed at buyers who wanted the brand’s most stylish and best-equipped body style rather than its cheapest transportation. Convertibles were always the smallest slice of any prewar Chevrolet’s production run, making a surviving example, restomodded or not, considerably scarcer today than the sedans and coupes that made up the bulk of 1940 sales.

The Restomod Formula

Swapping a small-block Chevy 350 into a prewar body is one of the most common and well-proven restomod paths in the hobby, favored because the engine is compact, reliable, inexpensive to source and rebuild, and backed by an enormous aftermarket of parts. Builders following this formula generally aim to keep the original sheet metal, cabin proportions, and overall silhouette intact while replacing everything mechanical underneath with something far easier to live with than a period-correct inline six.

What Changes Beyond The Engine

A 350 swap on a car this old is rarely done in isolation, since the original chassis, brakes, and electrical system were engineered around a much lighter, lower-revving six-cylinder engine. Builders taking on a swap like this typically pair it with upgraded brakes, revised suspension components, and a modernized wiring harness to actually make the added power usable and safe, though without documentation there’s no way to confirm exactly which companion upgrades this specific car received.

Era Rivals On The Showroom Floor

In 1940, Chevrolet’s Special Deluxe convertible competed against Ford’s Deluxe convertible and Plymouth’s Deluxe convertible, all three brands fighting for the same value-conscious but style-seeking buyer in the industry’s low-priced field. Chevrolet’s “Royal Clipper Styling” was a direct response to pressure from Ford’s own restyled 1940 lineup, part of an ongoing styling arms race among the era’s three low-priced leaders.

The Market For Prewar Restomods

Prewar restomods occupy a different collector niche than numbers-matching originals, appealing to buyers who want a car that’s genuinely enjoyable and reliable to drive on a modern road rather than a museum piece requiring careful, low-speed handling. That distinction generally keeps well-built prewar restomods more accessible than pristine original convertibles, even though both draw real attention at shows for very different reasons.

What To Check On A Car Like This

Buyers considering a prewar restomod should focus less on originality, since that’s explicitly not what this car offers, and more on the quality of the fabrication work: how cleanly the modern drivetrain was integrated, whether the chassis was reinforced appropriately for the added power, and whether the brakes and cooling system were upgraded to match. A dealer that discloses the swap upfront, as this listing does, is a better starting point than a private seller glossing over what’s actually under the hood.

Reading The Details In These Photos

The whitewall tires, chrome-heavy bumpers, and dual taillight bezels visible in these images are all consistent with the Special Deluxe’s top-tier trim, and the deep green paint paired with a lighter interior was a common, elegant combination on prewar convertibles of this class. None of these cosmetic details confirm anything about what’s under the hood, which is exactly why the drivetrain swap has to be evaluated separately from the car’s visual presentation.

Why Convertibles Command More Attention

Convertible body styles have always drawn outsized interest relative to their original production numbers, both because fewer were built to begin with and because open-top motoring carries a particular nostalgic appeal that closed cars from the same era rarely match. That dynamic holds true whether a convertible like this one is bone-stock original or, as here, extensively modified underneath its period-correct body.

The Bottom Line

This Special Deluxe splits the difference between prewar elegance and modern usability, wearing one of Chevrolet’s most graceful convertible bodies over a drivetrain that trades period authenticity for the kind of reliability a factory 216 six could never offer, a trade that suits buyers who want to actually drive their prewar Chevrolet rather than trailer it.
