Ford's 427 V8 was introduced in 1963 as a race-only engine. It was developed for NASCAR stock car racing, drag racing, and serious street racers. The true displacement of the 427 was actually 425 cu in (7 L), but Ford called it the 427 because 427 cu in (7 L) was the maximum displacement allowed by NASCAR. The stroke was the same as the 390 at 3.78 inches (96.01 mm), but the bore was increased to 4.23 inches (107.44 mm). The block was made of cast iron with an especially thickened deck to withstand higher compression. The cylinders were cast using cloverleaf molds—the corners were thicker all down the wall of each cylinder. Many 427s used a steel crankshaft and all were balanced internally. Most 427s used solid valve lifters with the exception of the 1968 block which was drilled for use with hydraulic lifters.

As an engine designed for racing it had many performance parts available for it, both from the factory and from the aftermarket.

Two different models of 427 block were produced, the 427 top oiler and 427 side oiler. The top oiler version was the earlier, and delivered oil to the cam and valvetrain first and the crank second. The side oiler block, introduced in 1965, sent oil to the crank first and the cam and valvetrain second. This was similar to the oiling design from the earlier Y-block. The engine was available with low-riser, mid-riser, or high-riser intake manifolds, and either single or double four-barrel carburetion on an aluminum manifold. Ford never released an official power rating. Other models were rated at over 400 horsepower (300 kW).

In addition, Ford also produced tunnel-port heads and matching intakes for the FE engine. These lacked the limitations imposed by the other intakes' need to squeeze the intake port between two pushrods by running the pushrods through the intake ports in brass tunnels.

The 427 FE engine is still a popular engine among Ford enthusiasts, some 40 years after winning Lemans.
