The AAR 'Cuda was Plymouth's homologation play for the 1970 SCCA Trans-Am racing series, named for the All American Racers Dan Gurney team that ran the works program. 1970-only — the Trans-Am series rule changes for 1971 ended the homologation requirement and the AAR with it.
Mechanical signature: a 340 LA-series small-block fitted with three two-barrel Holley carburetors on an Edelbrock aluminum intake (the same Six-Barrel induction logic as the V-code 440, scaled down). Side-exit exhaust through chambers ahead of the rear wheels. Fiberglass hood with a forward-facing scoop. Strobe-stripe body-side graphics. Optional 'AAR' callout on the rear quarter.
Designer — the AAR rides on John E. Herlitz's 1970 'Cuda body; the AAR-specific addenda (matte-black fiberglass hood, ducktail decklid spoiler, dive-plane front spoilers, side-exit exhaust callouts, strobe stripe) were engineering-and-graphics overlays produced by Chrysler's Trans-Am program team rather than a separate body design. Trans-Am program management was handled by Pete Hutchinson on the Plymouth side; Dan Gurney's All American Racers ran the works race effort that gave the package its name.
Plant identifier: AAR cars left Hamtramck with an 'M0-' prefix on the broadcast sheet's sequential build number, distinguishing them from regular-line 'Cuda BS29 cars. Plenum surfaces the prefix rather than treating it as an OCR error.
