Which 1970 Plymouth model featured a 340 Six Pack engine?

The 1970 Plymouth model associated with the 340 Six Pack engine was the AAR ‘Cuda. Built as a street version of Plymouth’s Trans-Am racing effort, the AAR ‘Cuda used a 340-cubic-inch V8 with three two-barrel carburetors, a configuration commonly called a Six Pack or Six-Barrel.

The package was more than an engine upgrade. AAR ‘Cudas featured a fiberglass hood, functional air induction, distinctive strobe-striping, staggered tires, heavy-duty suspension, and side-exit exhaust outlets. The model was produced only for 1970 to satisfy racing homologation requirements.

The regular 1970 ‘Cuda could also be ordered with a 340 V8, which causes a frequent mix-up. That standard 340 did not carry the special triple-carburetor Six Pack setup. The AAR version is therefore the precise Plymouth answer, while Dodge offered a closely related 340 Six Pack in the 1970 Challenger T/A.
