      The Plymouth Barracuda: First Pony (Fish?) Car

      From an article by Doug Zwick with material by Allpar and by Lanny Knutson.

      The Barracuda beat the Mustang to market by two weeks (April 1, 1964). A Valiant-based A-body from 1964 through 1969, it was replaced with the larger E-body version for 1970-74. (Development rationale and details.)

      The Valiant Barracudas (thanks, Jim Deane, for additions)

      Irving Ritchie, in the design studio, had the idea for making a sporty fastback version of the Valiant; it wasn't just a copy of the Ford Mustang, essentially the same idea applied to the Falcon, and at the same time.

      Unlike the Mustang, the 1964 Plymouh Barracuda was considered a Valiant, with a base 225 slant 6 and optional 180 horsepower (gross), 273 cubic inch V8. The V8 Barracudas would run 0-60 in 12.9 sec, and the quarter mile in 17.8 @ 72 mph, with an automatic (Car Life, July 1964). Gas mileage was 16-19. While most Valiants were sixes, 90% of buyers 1964 Barracudas were ordered with the V8.

      1964 was the only year that Barracuda had Plymouth, Valiant, and Barracuda badging. It also had the Valiant symbol used throughout instead of the later fish. Despite strong reviews for the Barracuda, the inexpensive, more clearly unique (as opposed to sedan-based) Ford Mustang outsold the Valiant model by 8:1.

      See the end of the page for 1965 specifications and a Plymouth Barracuda ad.

      By the end of the first generation (after the 1966 model year), the Commando 273 V8 - introduced in 1965 with the Formula S - was producing 235 HP. With 3.23:1 gears it would propel the Barracuda to 60 MPH in 10.3 sec, with the quarter coming up in 17.7 @ 79 MPH. (Road & Track, March 1966). Car & Driver got 0-60 in 9.1, and 1/4 mile in 17.6 @ 81 MPH (C&D, June/66). Both test cars had automatics.

      The Barracuda Formula S made a name for itself with its ability to corner better than most American (and European) cars; it provided a nice balance of acceleration and handling, with a European feel. Introduced in 1965, the Formula S had stiffer springing, front anti-roll bar, special badging, and most importantly, the 'Commando 273' engine, putting out a 'conservative' 235 hp. (Jim Deane wrote that most engine simulation programs put the Commando 273 at much higher levels.)

      Engines were the same in 1965 and 1966. The 4 speed was available from the introduction.

      Motor Trend tested an 1965 model with 3.55 gears and a 4-speed at 0-60 in 8.0 seconds, and the 1/4 mile in 16.1 @ 87 (MT, Jan/65). Though roughly the same as a 1995 Neon stick, these were excellent times for the day, when 0-60 in 12 seconds was considered pretty good (despite all those muscle cars, which were by no means what everyone drove).

      The first separate Plymouth Barracuda cars

      Deeper into the 1967 Plymouth Barracuda

      For 1967 the Barracuda was completely redesigned, and no longer shared any sheet metal with the Valiant. A coupe and convertible were added to the line. The engine bay of the A body was enlarged, so the 383 would fit (and fit it did, starting in 1967), and the 340 could be made optional in 1968. The 225 CID six would generate 0-60 times of 13.6 sec, and 1/4 mile in 19.4 @ 69.8 mph. The 273 V8 did 0-60 in 9.2 sec, quarter-mile in 16.9 @ 85.6 mph. Both test cars were automatics and 3.23:1 gears. (Car Life, March 1967)

      Because the engine bay was not that large, the 383 ended up with just 280 horsepower and 400 lb-ft of torque, down from the 325 hp and 425 lb-ft of torque seen in the bigger Belvedere and Fury.

      The new Barracuda, the product of the design team of Plymouth Chief Stylist Dick McAdam, was Chrysler's first application of the flowing-curves style introduced by General Motors in 1965, largely because Barracuda didn't have a sedan to compromise its sporty styling. The new Barracuda seemed purposely designed for the fastback style and, in a reversal of 1964, the hardtop and convertible seemed to be afterthoughts.

      With the three body styles, Barracuda matched Mustang, which had been marketing
      hardtops, fastbacks, and convertibles since 1965. However, Plymouth decided
      not to match Mustang's long-hood-short-deck dimensions that had also been
      adopted by the new-for-1967 Cougar, Camaro and Firebird. Ironically, Plymouth had championed the long-hood/short-deck
      style on its 1960 Valiant and 1962 Plymouth, but had quickly abandoned it.

      When Barracuda finally adopted the accepted sporty car
      dimensions in 1970, its profile appeared similar to that of the 1967 Camaro
      while, in another irony, the new 1970 Camaro sported a fastback roof that
      seemed to be a direct copy from the 1967 Barracuda.

      Thus, for all its new good looks, the Barracuda suddenly seemed a bit out of style. A driver sat higher in a Barracuda than in its competitors, comfortably practical but not as sporty.

      Restrictive exhaust manifolds (due to the tight engine bay space) helped keep the 383's horsepower down to 280, compared to its 325 hp counterpart in the bigger Plymouths. (The 325 hp version apparently did become available in the Barracuda later in the model year.) The big engine left room for neither air conditioning nor the power steering that would have been especially welcome in such a front-heavy car. Changing spark plugs on a hot engine was difficult. On the other hand, a relatively stock 1968 383 Barracuda ran the quarter in 14.20 @ 100+, using 3.23:1 gears and a 4-speed (Performance for the Chrysler Car Enthusiast, March 1992).

      The 340 cubic inch engine used starting in 1968 provided the best of both worlds: relatively light weight with amazing speed. A 1969 road test clocked the 340 A-fish at 7.1 sec 0-60, and 14.93 @ 96.6 in the quarter.

      The big news for 1968 A-bodies was the Super Stock 426 Hemi package, available in the Dart and Barracuda; around 50 of the latter were produced. This was a drag race only package, featuring a race-tuned Hemi and a seriously lightened body with acid-dipped doors, Lexan in place of glass, factory delete of anything not essential to life on the drag strip (e.g. back seat, sound deadener, window cranks). Lightweight van seats on aluminum brackets were used in place of the factory bench. They had a little sticker which indicated that the car was not for use on public highways, but for "supervised acceleration trials" only. It ran the quarter in the mid 10s in '68. Today [well, in the mid-1990s, when this paragraph was written], these cars dominate the top NHRA Super Stock classes (SS/A and SS/AA), and have broken into the eights! (Mopar Muscle Apr/94, Mopar Action Dec/93, Mopar Action Apr/94, Chrysler Power Mar/94). Spaulding Dodge also produced some 440 Barracudas in 1968, but these weren't true factory packages, even if they did masquerade as a "dealer installed option."

      Closer look at Rich Rinisland's 1969 Plymouth Barracuda.

      1969 saw the first appearance of the 'Cuda designation for a performance Barracuda package. A limited number of 440 Darts and Barracudas were produced. Car Life tested the 'Cuda 440 at 0-60 in 5.6 sec, and 14.0 @ 103 in the quarter mile. They were disappointed; they just couldn't get the car to hook up, it kept spinning the tires instead of racing down the track. (Car Life, June/69). Another period road test, reprinted in Musclecar magazine, backs up the 14-flat quarters, but they also tried it with ten-inch slicks, and ran low 12s. Modern street tires are better than those slicks ...

      The final Barracudas kept numerous reminders of their Valiant roots, in their basic exterior dimensions and dashboard shape, as well as a considerable amount of small hardware, but they were differentiated far enough that casual buyers would probably not see the similarities. Their place as "sporty Valiants" was taken over by the much more successful Plymouth Duster; while their name was applied to a much bigger car, one that could easily handle a 426 Hemi or 440 Six-Pack. Those Plymouth Barracudas or 'Cudas are in the next section... (click here)

      Hot rod builder George Poteet piloted his 1969 Blowfish Barracuda, powered by a Mopar 4-cylinder Midget engine and a Mopar Performance P5 Hemi head, to a new record in the Blown Fuel Competition Coupe/Sedan Class F with a run of 255.7 mph in August 2006. The pass bettered the previous record of 230 mph, set in 1990, by 25 mph.

      The Blowfish Barracuda project was first conceived during the 2004 Autorama in Detroit by Poteet and fellow car builder Troy Trepanier. Trepanier, along with his father Jack, built the car at their shop, Rad Rides by Troy, based in Illinois. Dodge Motorsports engineer Terry Dekoninck worked on aerodynamics with the group, with Mopar Performance engineer Jim Szilagyi also helping on the build as designer of the Mopar 4-cylinder Midget engine used in the 1969 Barracuda.

      The group, certain the record would fall entering the event, decided to run the car conservatively at about 950 horsepower but was confident another 500 horsepower could be added with slight modifications, enabling the Blowfish to run in the 280-plus mph range.

      Barracuda feedback and reviews

      1968 Barracuda 340-S (Steve Kokkins)

      I owned a blue 1968 Barracuda 340-S fastback from 1969 thru 1974. It had a 4-speed stick, 4-barrel Carter carb, a posi rear end, manual steering (!), and no A/C. I can personally attest to the great combination of decent handling (even with the Red Line stock tires) and power, although by modern standards it was fairly nose-heavy. Much better than the 383 which my buddy owned. I live in the Boston metro area, bought the car w/15K on it from Post Motors, a defunct Watertown MA Mopar dealer for about $2800.

      The manual steering was very heavy for parking and the clutch was heavy also (needed to transmit the torque, which was prodigious.) I had to sell it when I developed kneecap tendon problems from too-zealous workout squats, and could not use the clutch for any length of time. The gas crisis of '73 was a factor too. It required premium fuel. I miss it dearly today, and I regret selling it 35 years ago with 85,000 on it (for $600, and it needed work at the time).

      One thing not mentioned in your tech info was that it had a dual point distributor which wasn't easy (at least for me) to set up. One set determined the opening, and the other the closing; the dual points were needed, I think, to get enough current thru the coil. I still have some of the N9Y Champion plugs for it. I put on transistorized ignition to extend point life, although the rubbing blocks wore, requiring re-timing each year.

      In the snow (weekend ski runs up to Vermont), studded snow tires were needed on all four corners. Back then, you could get studded front winter tires, which did not have the huge aggressive tread of the rears, so handling on drier roads was not too scary. I remember some coming out like pistol shots at 85 mph, but it was the usual rear-drive muscle car in its behavior, which required a sensible attitude. I had just started being a pilot then (still am, with the geezer part of the US Coast Guard), so a little snakiness in the handling at speed was valuable for developing a light touch on the controls. We slept in it too, folding the seats down. I was in SCCA driving a Turner GT in D-Production, so it towed the race car trailer fine.

      1969 Barracuda 383 (Darrell Walls )

      I'm 60 years old and the only new car I ever bought was a 1969 Barracuda Coupe with a 383 and 4 speed with 323 gears. I out run most every thing I run except one 1969 Dodge Charger R/T 440. With his automatic trans he pulled me about a half car link and we stayed that way up to around 140 to 145 mph; we ran out of road and that was the only loss my Cuda ever handed me. Pound for pound, this was one hell-of-a-ride. I kept it 36 months and like a nut thought I needed something different. The only thing I ever did performance wise was to put a set of Mickey Thompson Super Scavenger headers on it. It was already fast, but this really helped, at least I thought it did. It also was a Formula S.


      Brakes were drum for each year, with front discs optional. The front suspension was torsion-bar; the rear was leaf-spring.

      The big E-body Plymouth Barracuda and Cuda: Plymouth's Challenger

      From an article by Doug Zwick with material by Allpar and by Lanny Knutson.

      The original Plymouth Barracuda was based on the little Valiant. Despite fine handling, it did not sell well; and the engine bay could barely hold a 340 V8, much less the huge 440.

      In 1965, Chrysler started working on a new version of the Barracuda, with the Plymouth Duster to replace it as the "sporty Valiant." Designer Carl Cameron refined the brand new Barracuda for some time, and, by 1968, they were building prototypes of what would be the 1970 cars.

      The E-body Plymouth Barracuda was created by merging A and B body components to fashion a sporty, attractive car that could handle any engine Chrysler had; some sources claim the suspension itself was designed by Bob Bachelor, adapted from one of the turbine cars.

      The new Barracuda was nearly the opposite of the original, capable of fitting a 440 or 426 Hemi, but not providing the same sports-car cornering as the older models.

      The Barracuda and Challenger design story

      by Diran Yazejian

      It was a Saturday during the summer of 1967. In the Dodge studio, Elwood Engel was happy with the Challenger proposal designed by Carl Cameron and okayed it to go into the theme approval the following Monday.

      Elwood then reviewed four body sides of the Plymouth Barracuda. He didn't like any of them. He pointed to four people and said, and I paraphrase, "We're coming in tomorrow (Sunday) to design a car." They were Milt Antonick, designer; Nick O'Shea, Jack Avoledo, and one other modeler whose name escapes me. On Monday morning, the body side of the '70 Barracuda, as we know it today, was ready for theme approval.

      The world will continue think of it as John Herlitz's design and legacy and so be it, but he wasn't even in the building on that Sunday.

      John understood and mastered form and surface development like no one else. He obviously did a great deal of refinement, and designed the front end and maybe the rear. I can't say enough about him as a designer and a gentleman.

      To have a launch in time for the 1970 model year, all parties agreed to pull-ahead the 1971 B body dash (firewall) and related components, already designed in engineering, which set the body width, cowl height, windshield shape, and belt height for the Barracuda and Challenger. [written later, in April 2016]

      In the Spring of 1968, both John Herlitz and I were promoted to Studio Manager level on the same day, he in Plymouth and I in Dodge, which made us eligible to lease company vehicles ordered per our specifications. For 1970, I ordered and leased a Challenger RTSE coupe with a 440 6-Pack, Plum Crazy with a red stripe on the rear. John leased a Barracuda convertible, triple black, 426 Hemi with a four speed trans. This is the car everyone is going crazy about today.

      At the end of the year, we turned in the old lease and picked up the new lease cars, '71s. My new one was a Charger and John's a Satellite, which he did design. With that, the Barracuda went to, who knows where, probably the auction! Remember, during that time nobody wanted performance cars.

      In the fall of 1969, the nearly identical 1970 Plymouth Barracuda and Dodge Challenger were introduced; the Dodge was two inches longer in wheelbase than the Plymouth. Both were made in hardtop and convertible versions. The E-bodies had a huge range of powerplants - from the slant six engine to the 426 Street Hemi, with just about every other engine in between, and a choice of four-speed sticks and tough three-speed TorqueFlite automatics.

      The 340 engine pushed out 275 hp (gross) and 340 lb-ft of torque at 3,200 rpm; the 340 Six Pack (triple two-barrel Carter carburetors) had the muscle of bigger engines with lower weight, helping traction and cornering.

      The 383 was up to 335 gross horsepower standard. Buyers could also get the legendary Hemi (425 hp), the 440 Magnum (375 hp with a single four-barrel carb), and the Hemi-challenging 440 Six Pack, with three two-barrel carburetors (390 gross hp and a stunning 480 lb-ft of torque at a very low 2,300 rpm).

      With the 340 engine, the 'Cuda seemed perfect for Trans Am racing, but the package didn't work as well as they had planned; traction remained an issue, and the AAR 'Cudas, though acid-dipped and weight-reduced, didn't remain in production long. (A small number were sold to the public, with reportedly poor worksmanship.) Tom Murden mentioned that the Plymouth 'Cuda was an inch too short for Can-Am, so the Challenger, being two inches longer, was raced there.

      A heavy duty TorqueFlite 727 automatic transmission was standard on the 440s and Hemi engines, with a four-speed manual (boasting a Hurst pistol-grip shifter and bulletproof Dana 60 rear axle) as an option; the TorqueFlite could outrun the manual.

      A limited slip differential, which would be a coveted feature, was optional, but a heavy duty suspension was standard across the R/T line. Even the Hemi was given 15-inch 60-series tires, which today are reserved for economy cars and family sedans.

      The dual-scoop hood pushed air into the engine bay, rather than forcing it into the engine; for that, you need the "shaker" hood, which was essentially an attachment to the air cleaner that protruded through the hood.

      For 1971, the Barracuda got a new grille designed to suggest barracuda fish teeth; both the E-bodies had quad headlights. Simulated chrome inset louvers suggested gills. The rear lights were modified, and large, flat-black decals covering most of the rear quarter panels, with engine size callouts on the doors, were optional; the shaker hood scoop was available on all 'Cuda models ('Cuda was a separate name for high-performance Barracudas).

      1971 ended up being the last year for the Barracuda convertible, with just 1,385 sales. Production was much more disappointing than in 1970, faling from 54,800 to 18,690.

      In 1972, horsepower ratings fell, and the various B engines disappeared; the 318 became the standard engine on all models with the 340 optional. Electronic ignition became available as an option.

      1973 Plymouth Barracudas

      by Lanny Knutson. Copyrighted by the Plymouth Bulletin. Reprinted by permission. Abridged from this original article.

      There were few visible differences between 1972 and 1973 Barracudas: the side marker light positions were slightly changed, a 'Cuda body-side stripe had a flat bottom edge, and there were impact-absorbing black rubber bumper guards. The latter didn't detract much from the lines of the original thin-line bumpers. But then, they didn't offer much extra protection either, except in head (or tail-) on situations.

      There were just two engines, the 318 standard engine in both the Barracuda and 'Cuda, and a detuned 340 optional in both. Included with the 340 was a non-functional twin scoop hood. It could also could be ordered with a flat black pattern treatment.

      Bucket seats were standard. A console and the Rallye Cluster instrument panel remained options. Standard 'Cuda (and 340) features were the scooped hood, heavy duty suspension, large tires, and a 7-blade Torquefan. It seems only 'Cudas got a body color grille and a black rear valence panel, and, if you wanted all the high-performance appearance features and suspension with a 318 engine, you could get them only if you ordered a 'Cuda.

      Although greatly downplayed from its splashy 1970 introduction, the Barracuda-Cuda series rebounded to a 22,213 sales total, up from the 18,450 sold in 1972 but less than half the 55,499 1970 total.

      The third-generation concept car, and the four-door concept

      Chad Imthurn wrote that the 1980s concept Cuda was in Mopar Collectors Guide. Two cars were made with rear window louvers and ground effect kits from the Shelby Chargers. Both cars were used for a driving school after they were done.

      The guys who created the 'Cuda drove it around Chrysler HQ and everbody liked it except for ... Carroll Shelby. He didn't like the idea of Plymouth making their own version of the Shelby Charger; he said it would take away the specialness of owning a Shelby Charger. Since Chrysler didn't want to offend Shelby this early in their relationship, the Cuda was dropped.

      Special 'Cuda

      Buzz Graves wrote: "I bought a 1970 U-code 'Cuda, built at the Los Angeles plant on 6-09-69, B5 blue with B5 interior, split bench seat with armrest, rubber front bumper, power everything, and A/C. It has the California Noise Reduction package, Six-Pack torsion bars, and even 440-6 emblems on the hood. ... it was original paint and where one emblem was removed, you could see the outline of 44-6.

      It had a "warranty motor" in it with no VIN stampings and the dimple on the side of the block where the metal tag usually goes on a warranty motor. It didn't have the original intake or carb. When we lifted the cover, I saw the HP2 stamping, external balancer, 6 quart oil pan, and the original six pack rods, pistons, and cam. It's stamped 5-9-69 on the block and the heads match the numbers.

      We discovered a green engineering change tag that had some faded writing ... we even gave it to a specialist at the police forensics lab. The result is we can see a date of 5/9/69, a 3x2 in the change box with some other number.

      Could it have been a specially changed car from the factory?

      What about the four-door Barracuda, whose photos have been shown around the Internet, and claims that four-doors were seen driving around Highland Park back in the 1970s? Designer Diran Yazejian wrote in April 2016,

      I have never seen nor heard of a 4 door 1970 E bodied Barracuda on paper, clay, sketch, or on a loading dock at Highland Park headquarters (if so, word of it would have spread like wild-fire) or any other form.

      I was a designer in the Dodge Exterior studio (from 1962 to 1972) during the time when the E-body was designed in 1967. There never even was any talk of a four door. Back then, it would be absurd to even propose or sketch one. Pony car coupes and convertibles were hot; sedans cold; and Chrysler was late getting into it. There was barely enough time for a pair of coupes and convertibles much less a sedan that nobody wanted anyway.

      AAR 'Cuda

      The AAR 'Cuda was an option package for the public to allow racing in Trans Am. A thousand cars, as required, were built and sold to the public. Ed Poplawski provided the following Product Planning letter, which was used to create the 'Cuda Trans Am (AAR 'Cuda).
