Ford 5.0 Coyote "Road Runner" specs: 302.7 ci (5.0L) 8-cylinder, 3.63 x 3.65 in (92.2 x 92.7 mm) bore and stroke, 11:1 compression. Rated 444 hp.
The Ford 5.0 Coyote "Road Runner" is close to square: 3.6299" bore against 3.6496" stroke, within 0.5%, 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. A rod ratio of 1.626 is in the range most production engines fall in. Each of the 8 cylinders displaces 37.8 ci (620 cc).
11:1 on aluminum heads is high enough that pump premium or better is normally required.
It is one of 12 engines in the Coyote family, the smallest at 302.7 ci. 2 factory variants share these dimensions, rated at 444 hp across 2012–2013.
