1970 Plymouth ‘Cuda: A Brief but Salient Overview

The 1970 Plymouth ‘Cuda hit the streets as a raw force in the muscle car wars. Plymouth took the Barracuda platform and sharpened it into the ‘Cuda badge, delivering aggressive looks and power that turned heads. This car stood out in a field packed with rivals like the Chevrolet Chevelle SS and Ford Mustang Mach 1. Buyers wanted speed and style. Plymouth answered with options from daily drivers to drag-strip monsters.

Design and Styling

The ‘Cuda’s body rode on the third-generation E-body platform shared with the Dodge Challenger. Designers gave it a fastback hardtop roofline that screamed performance. The front end featured a bold grille flanked by quad headlights. A long hood stretched back to emphasize the engine’s dominance. Fender flares wrapped the wheels for a planted stance.

Inside, the cabin mixed sport and comfort. Bucket seats cradled driver and passenger. A Hurst shifter dominated the floor in manual cars. The dash held full gauges, including a tachometer standard on V8 models. Woodgrain accents trimmed higher models. Plymouth offered the ‘Cuda as a 2-door hardtop or rare convertible. Base models started simple. Gran Coupe added upscale touches like vinyl tops and fancier interiors.

Colors ranged from Hemi Orange to Sassy Grass Green. Trim levels included base Barracuda, Gran Coupe, and full ‘Cuda with performance badging. Factory brochures showcased these options in vivid detail.

Engine Options and Performance Specs

Power choices defined the ‘Cuda. Start with the inline-six engines for economy. The 198-cubic-inch Slant Six made 125 horsepower. Step up to the 225-cubic-inch version at 145 horsepower. Both suited light duty.

V8s brought the fire. The 318-cubic-inch LA V8 with a 2-barrel carb delivered 230 horsepower. The 340-cubic-inch LA V8 punched harder. A 4-barrel with dual exhaust hit 275 horsepower. The AAR ‘Cuda variant tuned it to 290 horsepower with three 2-barrel carbs.

Mid-range 383-cubic-inch B and RB engines offered torque. The 2-barrel made 290 horsepower. The 4-barrel with dual exhaust reached 330. The Magnum version topped at 335 horsepower and 425 pound-feet of torque.

Big blocks ruled the top. The 440-cubic-inch RB Magnum with a 4-barrel Holley carb cranked 375 horsepower at 4,600 rpm and 480 pound-feet at 3,200 rpm. The king, the 426-cubic-inch Hemi, used two 4-barrel Carter carbs for 425 horsepower at 5,000 rpm and 490 pound-feet at 4,000 rpm. These SAE gross ratings captured the era’s brute force before net ratings took over.

California models dialed back power for emissions. They lost some ponies but kept the spirit.

Transmission and Driveline

Buyers picked from a 4-speed manual or TorqueFlite automatic. Manuals used a Hurst Competition/Plus shifter for quick shifts. Automatics handled daily driving with a console or column mount.

Rear-wheel drive sent power to a solid axle. Gear ratios varied by engine. High-performance cars got 3.54:1 or 3.91:1 rear ends. Sure-Grip limited-slip differentials locked power for traction. Dana 60 axles backed the Hemi.

Chassis, Suspension, and Dimensions

The ‘Cuda measured 186.7 inches long, 74.9 inches wide, and 108 inches between wheelbases. Height sat at 50.8 to 51.2 inches depending on tires and options. These dimensions made it nimble yet roomy.

Suspension used torsion bars up front and leaf springs rear. Heavy-duty setups stiffened high-power models. Shocks and sway bars tuned handling. Brakes combined 10.5-inch front discs on big-blocks with 10-inch drums rear. Power assist was optional.

Special Editions and Variants

The AAR ‘Cuda stood out as a NASCAR homologation special. It packed the 340 Six Pack engine, functional hood scoops, and racing stripes. Only 50 street versions left the factory.

Base models ran the 318 V8. Gran Coupe added luxury. Convertibles numbered just 774, all rare birds today. Hemi cars totaled 108 hardtops and 14 convertibles.

Production Numbers and Sales Performance

Plymouth built 39,249 V8 ‘Cudas in 1970. Manuals accounted for 9,026 units. Automatics took 30,223. Total Barracudas hit around 48,000 including sixes. V8s dominated sales at over 80 percent. Demand surged for performance amid tightening rules.

Pricing and Options

A base ‘Cuda hardtop started under $3,000. The 426 Hemi added a $1,228 premium. That pushed sticker prices near $4,500. Options like power steering, disc brakes, and Super Track Pak piled on costs. Rarity drove exclusivity.

Period Reviews and Performance Metrics

Quarter-mile times impressed. A 440 ‘Cuda ran low 14s. Hemis dipped into high 13s. Zero-to-60 came in under 6 seconds for big blocks. Fuel thirst hit single digits in hard driving.

Handling balanced straight-line speed. Ride stayed firm over bumps. It outpaced the Dodge Challenger in agility but matched the Camaro SS in drag races. Road tests praised the Hemi’s torque.

Legacy and Collector Value

The 1970 ‘Cuda marks the muscle car peak. Emissions laws soon choked power. Survivors fetch big money. Hemis top $200,000 at auction. Restorations demand original parts. Hemi examples draw crowds at shows.

Clubs keep the flame alive. Barn finds still surface. Values climb with concours quality.
