Ford Coyote specs: 307.4 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 38.4 ci (630 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 12 engines in the Coyote family, sitting between the 302.7 ci and 315.3 ci members. 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.
