Impala Engine Options: 1964

For 1964, the Impala saw no radical design changes, and even the engine options were a repeat of the previous year. However, the signature Impala six-light taillight assembly received an upside-down U-shaped aluminum trim strip above the taillights, and the individual lights were surrounded by a body-colored panel.

The 409 cubic-inch “big-block” came in three horsepower ratings in the 1964 Impala.

The big, “Jet Smooth” Chevrolet Impala, Bel Air, and Biscayne models returned, because the full-sized Chevy line up was known as a great car that delivered comfort and performance. The Impala not only remained the top of the line model offering, it actually became its own model, followed by the mid-line Bel Air, and then the affordable Biscayne.

With the Impala becoming its own model, that made it the second most expensive Chevrolet for 1964. Standard equipment included most of what was also available for Bel Air and Biscayne models, but also included some extra brightwork, and other creature-comfort features. It came as a four-door sedan, four-door hardtop sport sedan, two-door hardtop sport coupe, convertible, and a four-door (6 and 9 passenger) station wagon.

327

Once again, the 230 cubic-inch Turbo Thrift with 140 horsepower got you economical driving, without much oomph. The base V8 was the Turbo-Fire 283 cubic-inch small-block, delivering 195 horsepower, and optional 327 cubic-inch small-blocks with either 250 or 300 horsepower were available.

The 409 cubic-inch V8 returned as the big-block option, and was available in 340, 400, and 425-horsepower versions. With the milder 340 and 400 horsepower 409 cubic-inch engines, you got a single four-barrel carburetor. The 425-horsepower edition got you a more performance-built engine with twin four-barrel carburetors. When ordered new, you could place the 425 horsepower Turbo-Fire 409 V8 into any 1964 Chevrolet Biscayne, Bel Air, Impala, or Impala Super Sport.
