The AAR: A Tribute to All American Racers
The 1970 AAR Plymouth ‘Cuda was a limited production model they built to commemorate Dan Gurney’s All American Racers team. That is because they used ‘Cudas to compete in the Trans Am championships. It came with a 340 V8 small block and special plastic hood in matte black paint.
It also had a hood scoop, rear spoiler and interesting side graphics that included a big AAR logo. This version was somewhat more expensive than the regular 340 ‘Cuda. And that’s why they only made 2,724 of them.
