A well-preserved 1970 Plymouth 'Cuda wearing a coat of Lemon Twist paint over a black vinyl top has landed on eBay, listed by Arizona dealer Streetside Classics out of its Phoenix showroom. Finished with the E-body's signature twin-scoop hood and go-wing decklid spoiler, this two-door hardtop pairs its numbers-matching 340 cubic-inch V8 with a handful of tasteful upgrades that make it as easy to live with as it is to look at.
Rolling on 15-inch Mopar-style wheels wrapped in BF Goodrich Radial T/A rubber (235/60R15 up front, 255/60R15 out back), the car carries 340 hockey-stick side decals and chrome-tipped dual exhaust. Inside, black vinyl bucket seats flank a center console topped with the pistol-grip shifter that's become one of the most recognizable details of any automatic-equipped Mopar muscle car, while a factory-style AM/FM radio and a factory air conditioning system round out the cabin.
A 340 With Modern Manners
Under the hood, the numbers-matching 340 has been treated to an Edelbrock high-rise aluminum intake manifold and aluminum cylinder heads, fed by a Holley Sniper electronic fuel injection throttle body in place of the original carburetor. Power still routes through the factory-style A727 TorqueFlite 3-speed automatic and an 8 3/4-inch rear end, while a dual exhaust system with Street-Max mufflers and chrome tips supplies the soundtrack. Cooling duties fall to a larger aluminum radiator with dual electric fans, and the car retains its torsion-bar front and leaf-spring rear suspension along with power front disc brakes and power steering, so the upgrades add usability without disguising what the car is underneath.
What the Market Says About 340 'Cudas
The 1970 'Cuda's price spread is one of the widest in the muscle car hobby, and Hagerty Valuation Tools illustrates just how much engine choice matters. At the top end, a numbers-matching Hemi 'Cuda convertible in #3 (Good) condition carries an average value of roughly $1.55 million, while a 440 Six Pack convertible lands closer to $295,000 and a 383 four-barrel convertible sits around $122,000. Hardtops are considerably friendlier to the wallet: Hagerty pegs a 426 Hemi hardtop near $186,000, a 440 Six Pack hardtop around $77,200, and a 383 four-barrel hardtop at roughly $60,500 in #3 condition.
Small-block cars remain the most attainable entry point into 'Cuda ownership. Hagerty's guide doesn't break out a standalone line for a numbers-matching 1970 340 automatic like this one, but nearby comparables give a useful frame of reference: the six-barrel AAR 'Cuda 340 hardtop is valued around $70,200, and a 1971 'Cuda 340 tracks at roughly $60,900 for a hardtop and $95,600 for a convertible. Against that backdrop, this Lemon Twist car's $79,995 asking price sits in the same neighborhood as six-pack and big-block hardtop money, so buyers will want to weigh the EFI conversion and other upgrades against the originality premium that numbers-matching cars typically command.
Whatever it ultimately sells for, this 'Cuda is a reminder that the E-body market rewards documentation and drivability in equal measure. Numbers-matching engines, factory colors like Lemon Twist, and thoughtful mechanical updates all factor into where a car like this lands on the value spectrum, and listings such as this one are a good gauge of where sellers currently think that line falls.
