The 1956 model year

Overview

For 1956 the two-seat Thunderbird remained available as Ford body-model 40A with the folding top or 40B with the removable hardtop. Ford's revised factory specification separates the standard 292-cu-in V8 with conventional three-speed manual from the 312-cu-in V8 paired with overdrive or Fordomatic, so those powertrains are presented as distinct configurations rather than interchangeable options.

Year over year

What changed

  • Ford's factory matrix added the 312-cu-in V8 to the documented Thunderbird powertrain range.
  • The 292 V8 remained tied to the conventional three-speed manual, while the 312 was documented with overdrive or Fordomatic.

Worth knowing

Notable

  • Ford treated the folding-top and removable-hardtop cars as separate 40A and 40B body-model symbols while retaining one Thunderbird trim line.

Living with it

Reliability & ownership notes

  • Confirm the body-model, engine, and transmission from the vehicle identification and physical equipment before ordering restoration or service parts; Ford's factory matrix does not support every possible cross-combination.
  • Use the exact 1956 maintenance matrix for service timing and distinguish the 10,000-mile manual/overdrive lubricant duty from the 15,000-mile Fordomatic band adjustment and fluid change.
