1960 Chevrolet Chevy Impala Convertible in White & 348 Engine

A 1960 Chevrolet Impala convertible in Ermine White carries an engine option so rare that one longtime fan estimates only a few hundred were built this way: the 348 Tri-Power, three two-barrel carburetors feeding a car most buyers ordered with a single four-barrel instead. Volo Auto Museum’s Brian Grams walks through this loaded survivor with My Car Story host Lou Costabile, and the story it tells — from Sydney to a car show price tag decades later — says a lot about how these cars are valued today. Watch to see what made this one worth keeping.

A 1960 Chevrolet Impala convertible doesn’t need much of an introduction — Ermine White paint, acres of chrome, a top that folds away for anyone who ever wanted to feel like they were driving something off a movie poster. But underneath that hood at Volo Auto Museum sits an option so specific that even seasoned collectors have to do the math to figure out how few were built this way: three two-barrel carburetors, no automatic-only shortcuts, and a drivetrain combination that one longtime commenter says probably numbered only a few hundred cars total. The story behind why gets more interesting the closer you look.

The Tri-Power Option Nobody Ordered Casually

The 348 cubic-inch V8 with Tri-Power induction — three two-barrel carburetors feeding one engine — wasn’t the default choice for a 1960 Impala buyer, and pairing it with a manual transmission and the top-of-the-line convertible body made this combination genuinely scarce. One commenter who has studied these cars closely puts the total production of Impalas built with every one of these options — tri-power, convertible, the works — at only a few hundred units, out of a model year that sold in the hundreds of thousands.

Where This Car Lives Now

Volo Auto Museum’s Brian Grams walks host Lou Costabile through the car in Volo, Illinois, part of a rotating inventory that mixes Hollywood picture cars, military vehicles, and classic muscle under one roof. The museum’s approach has always leaned toward cars people can actually see running — engine fired up, doors open, history explained on camera — rather than static roped-off displays, which is exactly the treatment this Impala gets.

A Design Language That Still Stops Traffic

One viewer describes the late-1950s-into-1960 Chevrolet lineup as looking like it was doing fifty miles an hour while parked, and it’s hard to argue — the era’s obsession with jet-age styling and the recent breaking of the sound barrier bled directly into automotive design, batwing tailfins and all. That same commenter notes the Australian market received right-hand-drive versions built in Canada specifically for British Commonwealth countries, with a dashboard designed for an easy left-to-right switchover, a detail most American owners never think to look for.

What These Cars Actually Cost Buyers, Then and Now

A commenter who bought a six-month-old ’60 Impala convertible — black inside and out, that same 348 Tri-Power, Duntov cam, close-ratio four-speed, high-speed lifters — paid $2,700 for it used. Decades later, another owner recalls being offered a similar example with a continental kit for $25,000 at a car show in the late 2000s, a gap that says as much about how the collector market has re-rated these cars as it does about inflation.

The Detail Even Fans Get Wrong

A sharp-eyed commenter flags an inconsistency worth noting for anyone chasing period-correct restorations: this particular Impala’s firewall was repainted body color rather than the black it left the factory with. It’s the kind of detail that separates a genuinely correct restoration from one that merely looks the part, and it’s exactly the sort of thing Volo’s on-camera walkarounds tend to surface that a photo alone never would.

A Car That Crosses Continents and Generations

The comment section reads like a reunion — a viewer in Sydney remembers his family’s example from 1960, another in India says the same body style still shows up in wedding processions there today, and more than one American commenter ties the car directly to a parent who has since passed away. Few cars generate that specific mix of global reach and personal memory in a single comment thread.

Why the Top-Spec Convertible Still Wins

Between the styling, the rare drivetrain, and the sheer number of owners who call it a dream car decades after the fact, this Impala represents the ceiling of what a 1960 Chevrolet full-size could be ordered as — not a stripped six-cylinder sedan, but the loaded convertible with every performance option checked. That’s precisely the kind of car Volo Auto Museum built its reputation on finding.

How the Tri-Power Impala Stacks Up Against ’60 Rivals

Ford’s 1960 Galaxie Sunliner convertible and Chrysler’s 300F offered comparable full-size performance and prestige that same model year, but neither matched the specific combination Chevrolet buyers could order into an Impala: three carburetors feeding a genuinely potent 348, wrapped in the division’s flagship convertible body. Where the 300F leaned on sheer displacement and Ford’s best full-size offerings leaned on styling, the Tri-Power Impala split the difference, delivering both looks and a drivetrain serious enough to embarrass unsuspecting rivals at a stoplight.

The Restoration Math Behind a Car Like This

Finding date-correct Tri-Power carburetors, the specific Duntov-cam-equipped 348 short block, and the manual transmission this car was built with has become one of the harder restoration puzzles in the full-size Chevrolet hobby, since most surviving 1960 Impalas were ordered with the base engine and Powerglide automatic. Restorers chasing a genuinely correct build often spend years sourcing parts that were never common even when new, which is part of why a documented, running example carries more weight with serious collectors than a car that merely looks the part.

Why Full-Size Performance Convertibles Still Draw a Crowd

Full-size performance convertibles like this one occupy a different collector niche than their mid-size muscle car descendants — less about quarter-mile bragging rights and more about presence, comfort, and the specific late-1950s optimism baked into the styling. That’s part of why the comment section skews so heavily toward memory and family history rather than spec-sheet arguments; a car this size, with this much presence, tends to attach itself to personal history rather than performance rivalries.

The Cost of Keeping One Running Today

Tri-Power carburetor synchronization is notoriously finicky by modern standards, and keeping all three carbs balanced with correctly functioning vacuum-secondary linkages requires a specialist familiar with GM’s early-1960s induction systems rather than a general classic car mechanic. That specialized upkeep is part of why so many original Tri-Power setups got swapped for simpler single four-barrel carburetors over the decades whenever an owner just wanted a reliable driver rather than a numbers-matching survivor, which in turn makes a genuinely unmolested example like this one increasingly valuable simply for having survived unmodified this long. Parts suppliers who specialize in NOS and reproduction Rochester carburetor kits for the 348 Tri-Power setup have become a small cottage industry of their own, since a full rebuild kit for all three carburetors, correctly matched, isn’t something a typical parts store stocks off the shelf.
