This 1970 Plymouth ‘Cuda AAR exists because of a rulebook, not a marketing plan. Plymouth had to sell thousands of street versions just to make its Trans-Am racecar legal to compete. Under the fiberglass hood is a 340 ‘Six Barrel’ V8 that Plymouth badged differently than Dodge’s identical engine, backed by a factory rating widely believed to undersell its real output. Only 2,724 were built, all within a single five-week window in early 1970. That narrow build window is exactly what makes cars like this Moulin Rouge example so sought after today.
