Pontiac sold the GTO as an option package, with a 325-horsepower base engine and an optional 348-horsepower Tri-Power configuration, according to the General Motors Heritage Collection.
The idea became a landmark in muscle-car history not because the GTO was literally forgotten, but because a practical fit between a larger engine and a lighter car helped create a new performance formula. GM Heritage identifies the 1964 Tempest LeMans with the GTO option as the car that started the muscle-car era.
What engine did Pontiac put in the GTO?
The 1964 GTO package used Pontiac’s 389-cubic-inch V8 in place of the Tempest’s standard 326. General Motors says the 389 came from the full-size Grand Prix. The package combined that engine with dual exhausts, GTO nameplates, engine-turned dash inserts and dual hood scoops.
Not every 1964 GTO had the same engine configuration. GM Heritage lists 325 horsepower for the base 389 and 348 horsepower for the optional Tri-Power version. The horsepower figure depends on which configuration is being discussed.

How the 389 fit the Tempest
The key was a straightforward fit in the Tempest platform, rather than a radical, extensively documented engineering conversion. In a 2025 retrospective, GM recounts that John DeLorean, then Pontiac’s chief engineer, wanted a 389 in the prototype. The account, drawing on Jim Wangers’ later book, says engineer Bill Collins noted that shared engine mounts made the installation straightforward. Savoy Automobile Museum also describes a 389-powered Tempest experimental project associated with Collins and DeLorean.
These development details come from retrospective accounts, not a contemporaneous verbatim record. The familiar prototype story is best treated as recollected history, with credit and anecdotal details attributed to the sources recounting it.

How the GTO package compared
| 1964 Tempest configuration | Engine | Stated horsepower | What it means |
|---|---|---|---|
| Standard Tempest | 326-cubic-inch V8 | Not specified in the cited GTO figures | The engine replaced by the GTO package’s 389 |
| GTO package, base configuration | 389-cubic-inch V8 | 325 hp | GM Heritage’s base GTO figure |
| GTO package, optional Tri-Power | 389-cubic-inch V8 | 348 hp | Optional higher-output configuration |
These figures are from the General Motors Heritage Collection. Its 0–60 mph figure of 7.7 seconds applies to the 325-horsepower car; it should not be presented as a test result for every GTO configuration.
Was the first GTO a separate model?
No. Pontiac initially offered the GTO as a sport option package for the 1964 Tempest, rather than as a separate model line. GM’s retrospective says DeLorean played a major role in its development. The option-package approach let Pontiac offer the performance combination within the Tempest range.

Why the 1964 GTO mattered
The GTO paired an intermediate car with a larger V8, turning engine fitment into a compelling performance package. Its importance lies in that combination: the Tempest’s platform, the 389 from the Grand Prix, and a clearly differentiated option with its own equipment and identity.
GM Heritage reports that 32,450 Tempests were sold with the GTO package for the 1964 model year. It also identifies the car as the start of the muscle-car era. Those figures and descriptions are GM Heritage’s; other accounts may report different sales totals, so they should not be blended without explaining the source.
