1971 Plymouth Barracuda 6.1L EFI HEMI 5 Speed XV Level II

Check out this wicked 1971 Plymouth ‘Cuda. The beneficiary of a nut-and-bolt, rotisserie restoration that included a modern 6.1 liter Hemi, a complete XV suspension and a modified leather interior, it’s an exceptionally well-done piece that’ll more than hold its own against any pampered show queen. And, although it doesn’t have factory documentation or a stack of plastic trophies, it does have a feature article in the June 2008 edition of Super Rod Magazine.


Raise the wide red hood and you’ll find a killer, XV-tweaked V8 that takes this Plymouth from ‘very appealing’ to ‘MUST HAVE’ almost as fast as it takes its driver from ‘confident’ to ‘scared stiff’.
Measuring exactly 6.1 liters, Chrysler’s resurrected Hemi uses a revised block, a forged crank, lighter pistons, strengthened rods, new oil jets, variable cam timing and increased flow heads to turn 10.3 to 1 compression into 425 horsepower.
A custom-grind cam, balancing and blueprinting the whole set-up and throwing in a bunch of hand-picked bolt-ons. The result is a healthy 525 horsepower that’s fun, reliable and easy to live with. At the top of the stout block, a bright red shaker funnels wind through a billet, plate-style throttle body in to an aluminum single-plane intake. That air mixes with fossils thanks to a custom-tuned engine management system, which controls a tweaked fuel supply via billet rails, an adjustable regulator, stainless lines, a high-flow filter and a custom tank.
That air/fuel mixture explodes under extended RPM valve springs. Those valves feed 304 stainless headers, which flow in to 2.5-inch 304 stainless pipes. And cooling for that cycle is provided by a beefy aluminum radiator, which is equipped with two electric puller fans. Visually, the body-matched bay comes together every bit as well as the outside of the car, with its smooth firewall and bright red fenders providing a perfect frame for the modern Chrysler mill.


Speaking of that mill, its installation is exceptionally well done and certainly looks tidy enough to pass as an OEM package. And, in addition to precise XV bracing, the powerplant features a host of first class ancillary components including an aluminum oil pan, AN fittings and hydraulic hood supports.
