Plymouth Barracuda 1970 – 550HP Supercharged – Amazing V8 Sound!

A factory 440-equipped 1970 ‘Cuda was already a rare find, with only a few hundred hardtops ever built with that combination. This particular build takes that same big block architecture and adds a supercharger, claiming 550 horsepower in the process. It’s proof that the E-body platform Plymouth engineered over fifty years ago still has plenty of room to grow. Here’s how rare the original combination was, and what it takes to push it this far today.

An ultra clean 1970 PRO TOURING Plymouth ‘Cuda with a custom supercharged 7.2L 440 big block V8 engine delivering 550 horsepower!!

Plymouth's engineers gave the 1970 'Cuda a factory 440 option that could already embarrass a Corvette in a stoplight race, but this particular build wasn't satisfied leaving things at factory spec. A supercharger now sits on top of that same 7.2 liter big block, pushing output to a claimed 550 horsepower in a body that was already one of the rarest Barracuda configurations Plymouth ever built. Original 440-equipped 'Cudas were never common to begin with, and modern builders have spent the years since finding creative ways to push that same architecture even further. So what does it actually take to turn a fifty-year-old big block into a 550 horsepower street machine, and how rare was this configuration to start with?

How Rare Was A Factory 440 ‘Cuda?

Plymouth's factory 440 came in two flavors for 1970: a four-barrel Super Commando rated at 375 horsepower, and the 440 Six Barrel with triple two-barrel carburetors rated at 390 horsepower. Despite the performance on offer, only 618 hardtops left the factory with the 440 four-barrel paired to a TorqueFlite automatic, and just 334 more got the same engine with a four-speed manual, making any factory 440 'Cuda a genuine rarity even by muscle car standards.

Building 550 Horsepower The Modern Way

Contemporary pro-touring builds take that already-potent 440 architecture and push it considerably further, with some builders boring and stroking the block out to as much as 512 cubic inches while others bolt on forced induction instead. A supercharged 440 like the one under this 'Cuda's hood blends factory-era displacement with modern boost technology, delivering the kind of power that would have been unthinkable even to the engineers who built the original Six Barrel option back in 1970.
