1971 was the only year Plymouth gave the ‘Cuda four headlights and strange fender-mounted gills — a look the brand tried once and never repeated. Under that one-year-only face sat six possible engines, topped by a 426 Hemi in its final season, and a convertible body so rare that only a handful were ever built with a manual transmission. Here’s what made this single model year one of the most collectible in Mopar history.
Amazing ‘Cuda!!
Some years a car changes so completely that collectors can spot it from fifty feet without reading a single badge. 1971 was that year for the Plymouth ‘Cuda. Quad headlights replaced the previous single-lamp face, and strange fender-mounted gills appeared on the body sides — styling cues Plymouth used for exactly one model year and never again. Underneath that one-year-only sheet metal sat as many as six different engines, from a mild 340 up to the fire-breathing 426 Hemi in its final season of production. Somewhere in that lineup is a variant so rare that fewer than ten were ever built. Which one?

A Face Plymouth Only Wore Once
The 1971 Barracuda and ‘Cuda received a mid-cycle facelift that gave the car four headlights instead of two, along with distinctive fender gills — both details unique to this single model year before Plymouth reverted the design for 1972. Combined with a new grille and revised taillights, the changes gave the ’71 ‘Cuda a more aggressive face than its 1970 predecessor, one that collectors today use to instantly date a car at a glance. Plymouth also revised the taillights and rear valance that year, rounding out a refresh substantial enough that even casual observers could date the car without checking a VIN.
Six Engines, One Very Short List at the Top
Buyers choosing a 1971 ‘Cuda picked from a 340, a 383 (rated 300 horsepower and 410 lb-ft, good for a quarter-mile in under 17 seconds), a 440 Magnum, a 440 Six-Barrel, and — at the very top — the 426 Hemi, in its last year of availability in the Barracuda body. Only 108 ‘Cudas were built with the 440-6bbl paired to a 4-speed manual that year, and Hemi convertibles with a stick shift number in the single digits, making them among the rarest muscle cars Detroit ever produced. A 440 Magnum-equipped ‘Cuda, meanwhile, offered a middle ground: less exotic than the Hemi but still capable of strong quarter-mile times with the right gearing, making it the engine most buyers actually drove home.
Why the Convertible Matters Most
Of the roughly 16,000-plus Barracudas Plymouth built for 1971, only a few hundred were convertible ‘Cudas, and a mere handful combined that open-top body with the 426 Hemi and manual transmission. That scarcity is exactly why 1971 Hemi ‘Cuda convertibles now rank among the most valuable American muscle cars sold at auction, often changing hands for seven-figure sums. Even a standard-engine ‘Cuda from 1971 has become increasingly collectible simply because of that one-year-only styling, regardless of what’s under the hood.
