1970 Plymouth Barracuda Convertible: A One-Owner E-Body With A Slant Six

The 1970 Plymouth Barracuda is one of Mopar’s most cherished pony/muscle cars, and also one of its greatest mistakes; just when the pony car market began to deflate, here came a full-bore redesign from the Pentastar that was several years too late. But even though the Barracuda didn’t sell well when new, people are more than willing to pay for them now, even when they’re powered by the base Slant Six as this example is. It’s a one-owner car with an interesting option or two that’s for sale on Hemmings Auctions in Jacksonville, Florida.

The overall condition of this Barracuda is that of an older cosmetic restoration combined with a reasonably well-preserved original. It was repainted in its original Rallye Red back in 1980, but there’s plenty of orange peel and some rust bubbles in the lower quarters. As you can see, the bumper and lower valance panel took a shot from something over the past 56 years, but with any luck, the bumper could be leveled by replacing or bending a bumper bracket.

The engine, the 145-horsepower, 225-cubic-inch Slant Six, belies the Barracuda’s muscular looks, but it’s one of Chrysler’s most heralded engines for its durability and simplicity. It’s combined with Chrysler’s equally durable TorqueFlite automatic, which has recently been rebuilt. Beneath the air cleaner is Holley’s notoriously leaky 1920 one-barrel carburetor, which has also been gone through, and other “work included replacement of belts, hoses, and gaskets, as well as a tune-up.”

I mentioned that this convertible has an interesting option or two. Power steering is probably unnecessary on a Slant Six car, but it’s not really a surprise; however, ordering front power disc brakes on a Slant Six car definitely is, and this car has them. They’ve been refurbished in preparation for the car’s sale, as has the suspension and steering (but no specific details have been shared on that front).

The interior is standard Barracuda, with a very monochromatic look aside from the woodgrain console with sporty floor shifter. You can see that there’s a crack in the dash pad and most likely a few on the steering wheel, judging by the aftermarket cover.

The driver seat is showing some wear, but upholstery kits are available from Legendary Auto Interiors, albeit with a potential 112-day lead time.

I have no idea what’s going on in the trunk, but it appears to have been coated in bedliner or something similar.

1970 Plymouth Barracuda gas tank and undercarriage

The undercarriage is crusty looking, but none of the pictures (which are all unfortunately shot at this low angle) show any cause for structural concern. I believe the rear end is Chrysler’s light-duty 7 1/4-inch unit, which carried standard 2.76:1 gears with a 225/TorqueFlite combination. Given current gas prices, this might be one of the better buys in terms of economy, as the new owner could theoretically enjoy 20-plus miles per gallon in steady-state driving, not bad for an old American car.

And a good, solid driver it seems to be. It has new tires and seems to be road ready as it sits, but my greatest fear for the car is that it becomes fodder for another ‘Cuda tribute. Your car, your choice, but considering that only 158 225/TorqueFlite convertibles were built in 1970 (according to Hemmings), it’s probably rarer as it sits. As for me, I’d be content to lower the top and hit the slow lane in style.
