1970 Plymouth 'Cuda 440 Six Barrel
The 440 Six Barrel put Plymouth's triple-carbureted RB big-block into the new-for-1970 E-body 'Cuda. Factory literature called the engine the 440 Six Barrel; the equivalent Dodge induction was marketed as the Six Pack. Rated at 390 gross horsepower and 490 lb-ft, it used three Holley two-barrel carburetors and was paired with either the A833 four-speed or heavy-duty 727 TorqueFlite automatic.
The package brought heavy-duty drivetrain and chassis requirements, while axle ratio, Sure-Grip, power assist, wheels, hood equipment, and cabin choices still depended on the original order. The optional N96 Shaker is one of the model's best-known features, but a shaker opening or 440+6 badge does not prove how a particular car was built.
The cited secondary production table reports 1,755 hardtops and 29 convertibles, or 1,784 1970 'Cudas with the 440 Six Barrel. Hemmings independently reports the same combined total. These figures remain attributed rather than represented as a surviving Chrysler production ledger.
Fourteen documented finishes and the recorded hood, stripe, wheel, instrument, seat, and console choices show how much two authentic cars can differ. Each car's original combination must be reconciled with its VIN, fender tag, broadcast sheet, body numbers, hidden paint, and drivetrain stampings.
For authentication, begin with the V engine character in the VIN and E87 engine sales code, then verify the carburetion, transmission, axle, body stampings, documents, paint, and trim. Installed equipment, badges, or appearance alone cannot establish factory 440 Six Barrel identity.
