This specific model, 40193, is the verified fitment for 1966 Chevrolet and Chevelle applications equipped with 396 and 427 cubic inch V8 engines. It is engineered specifically for performance levels including the 325HP and 360HP versions of the 396, as well as the 390HP configuration of the 427.

It provides the high-volume fuel delivery required by Chevrolet’s standard performance big-block powerplants while excluding Special High Performance (e.g., 375HP/425HP) configurations.
