Plymouth’s A51 Twister package put the Duster 340’s grille, stripes and even its hood scoops on cars powered by a 145-horsepower slant six, and Dodge did the same thing with the Demon Sizzler. Half a century later, buyers are still confusing them with the genuine article. Here is exactly what separated the look from the muscle.
Plymouth’s 1971 Duster 340 wore a compact-car body and a shark-tooth grille, but its 340-cubic-inch small-block gave it enough power-to-weight advantage to hunt down muscle cars costing twice as much. Motor & Mutt TV makes the case for this overlooked Mopar as one of the smartest performance buys of its era. Watch to see why enthusiasts still argue over exactly what’s under the hood.
David Freiburger and Steve Dulcich built The Red Duster, a budget 1971 Plymouth Duster with a 360 and a four-speed, on Roadkill Garage — then Freiburger hit the road to visit Dulcich once the wrenching wrapped up. A 2023 Dodge Challenger Scat Pack giveaway rides along with the build. It’s a low-buck muscle car with a surprisingly high-value payoff.
Aedan’s family bought this 1970 Plymouth Duster 340 new — and nobody had driven it in thirty years. Tom’s Refurb brought it back to life in a single week, rust patches and all, ending with a burnout that had viewers’ jaws on the floor. One commenter, a mechanic with fifty-four years of experience, said he’d never been more impressed. See how a generational survivor got its attitude back.
No power adders, no aftermarket engine swaps, no cheating allowed: just two genuinely stock muscle cars from two different eras, lined up side by side at a drag strip built entirely around one strict rule. A rare COPO-built 427 Chevelle and a compact Plymouth Duster 340 went head to head at this event, and the comment section is already arguing about whether either car was actually as stock as advertised.
A handful of factory Mopars slipped through Mecum Kissimmee 2026 for prices that left the room stunned — a letter-series 300 for around $30,000, a 440-powered ‘Cuda, a Coronet R/T one viewer called the best deal of the weekend. Dealers noticed first, and they’re already marking these cars up. Which ones got away, and what should have sold for twice as much?
Vice Grip Garage’s 1973 Plymouth Duster is losing its famously indestructible slant six and weak 904 automatic, but what Derek drops in their place isn’t the Mopar-correct choice anyone expected. A 351-based stroker, paired with a heavy-duty 727 TorqueFlite, sends this budget-performance fastback in a direction that’s already sparking debate among Mopar loyalists in the comments. Longtime fans are also reminiscing about their own Duster and Dart memories along the way. See exactly what Derek chose to build this Duster around, and why it’s dividing the Mopar faithful.
