Impressively engineered 

Chevrolet Performance engineers adapted a unique, electronically controlled port fuel-injection system to the ZZ6 350, using an aluminum intake manifold that has the appearance of a carbureted intake. A fuel-injection throttle body mounted in place of the carburetor allows a traditional air filter to be installed on the engine. The Deluxe package includes the distributor, damper, and flexplate.
