[427TJ]

Motion Performance prepped all kinds of cars, not just Chevs. You're probably thinking of the Motion shop's connection to Baldwin Chevrolet which gave birth to the "Phase" cars: Camaro, Corvette, Nova, Chevelle. One of the more well-known Ford projects Motion handled was a pair of Cobra Dragonsnakes, the first being a 289 and later a 427. The picture shows Joel Rosen dyno-tuning a 289 Dragonsnake at the Motion shop. Note the trophies up on the wall!
