The Corvette was fitted with the Rochester RamJet and RAM’s horn intake as the RPO Code 579D. But recently during some research I read that there was another modification.
It was called the Air Box Option, RPO 579E and it was perhaps the first production cold air induction system(at least for Chevy).
It consisted of a plenum box mounted on the fender well of the driver’s side. The box was fitted to an opening in the bulkhead next to the radiator with an air filter inside. The duck work ran to the fuelies injection unit.
Records indicate that there were only 43 produced in 1957.
Thanks for Reading.
