See other engines in this family

Ford Coyote specs: 302.7 ci (5.0L) 8-cylinder, 3.661 x 3.65 in (93 x 92.7 mm) bore and stroke, 12:1 compression. Rated 460-500 hp. Rod ratio and piston speed.

The Ford Coyote is close to square: 3.6614" bore against 3.6496" stroke, within 0.3%, which splits the difference between a high-revving layout and a torque layout. The 3.6496" stroke puts mean piston speed at 4,000 ft/min around 6,600 RPM, which is where a production bottom end is generally considered at its limit. Each of the 8 cylinders displaces 37.8 ci (620 cc).

12:1 on aluminum heads is high for a production gasoline engine; running a ratio like that on pump fuel depends on chamber design and fuel delivery rather than the number alone.

It is one of 4 engines in the Coyote family, the smallest at 302.7 ci. 3 factory variants share these dimensions, rated from 460 to 500 hp. Factory fitments include the Ford Mustang GT, Ford F-150, Ford Mustang Dark Horse and 1 other.
