The 1957 Ford Thunderbird is an iconic American car from the late 1950s. Produced by Ford Motor Company, the Thunderbird was originally introduced in 1955 as a sporty two-seat convertible aimed at luxury buyers. The 1957 model year brought some significant changes to the Thunderbird, including the addition of a back seat to make it a four-seater.
The 1957 Thunderbird came in three trim versions, distinguished by an alphabetical code – E, F, and H. The E code Thunderbird was the base model, while the F and H codes added additional features and amenities. All three 1957 Thunderbirds came equipped with V8 engines, but the exact engine differed depending on the trim level.
1957 Thunderbird E Code Overview
The 1957 Thunderbird E code was the most affordable and basic trim option that year. As the entry-level Thunderbird, it came standard with a 312 cubic inch (5.1 L) V8 engine producing 245 horsepower. This engine, known as the Y-block V8 for its deep-skirt block design, had a larger bore and shorter stroke compared to other Ford V8s of the era.
Some key features of the 1957 Thunderbird E code included:
- 312 cubic inch V8 engine
- Single four-barrel carburetor
- Dual exhaust system
- Three-speed manual transmission
- 102 inch wheelbase
- Drum brakes
- Solid color exterior paint
- Vinyl interior
Being the base model, the E code did not include some features found on the higher F and H code cars, such as power steering, power brakes, and upgraded trim. However, it provided an affordable starting point for access to the fun and stylish new Thunderbird.

312 Y-Block V8 Engine Background
The 312 cubic inch V8 fitted in the 1957 Thunderbird E code was part of Ford’s Y-block engine family, sometimes referred to as the Y-block V8. It earned this nickname due to its deep-skirt block design that looked like a “Y” when viewed from the side. Other members of the Y-block family included 272, 292, and 312 cubic inch displacements.
Some key facts about the Y-block V8:
– Introduced in 1954 to replace Ford’s flathead V8

– Actual displacement is 317.5 cubic inches
– Short stroke allowed higher RPM operation

The Y-block was Ford’s first overhead valve V8 engine, marking a major redesign from the flathead V8. It provided substantially more power, efficiency, and durability than the outdated flathead. The 312 was the largest version of the Y-block family, making it well-suited for the Thunderbird. It continued Ford’s reputation for offering powerful easy-breathing V8s to the masses.
