As blue-chip muscle cars go, the Hemi-powered Plymouth ’Cuda lies at the top of the heap. For 1970 and 1971, the Barracuda and Barracuda Gran Coupe had two six-cylinder engines available — a new 198 cu in (3.2 L) version of the slant-6, and the 225 — as well as three different V8s: the 318ci, the 383ci with two-barrel carburetor and single exhaust, and the 383ci with four-barrel carburetor and dual exhaust 330 hp (250 kW) SAE gross.
The Cuda had the 383ci 335 hp (250 kW) SAE gross (same as Dodge’s 383 Magnum) as the standard engine. It also had the 440ci four-barrel Super Commando, the 440ci six-barrel Super Commando Six Pak, and the 426ci Hemi. The 440- and Hemi-equipped cars received upgraded suspension components and structural reinforcements to help transfer the power to the road.
