The Pontiac 389 engine is an iconic powerplant in American automotive history, having been first released in 1959 as an upgrade option to the existing Pontiac 287 engine. Since then, the 389 has been popular amongst performance enthusiasts, with its large displacement and robust design. But is it classified as a “big block” engine? The answer is yes – the Pontiac 389 is considered a big block engine, which means it has a taller, wider, and heavier construction than traditional small block engines. This makes it ideal for applications that require more power and torque, such as drag racing or off-roading. This article will explore the history of the Pontiac 389, its unique design, and performance applications.

In terms of displacement, there was no comparable engine between the muscle cars and full-size models offered by Oldsmobile, Buick, or Pontiac, but these engines did share some characteristics.
