Ultimately, the big difference between the Gen 2 and Gen 3 Coyote engines is the amount of power they can generate. The Gen 2 version was no slouch in that department, with it being able to reach up to 435 hp with a peak torque of 400 lb-ft. When the Gen 3 Coyote came around, Ford was able to amplify those numbers to 460 hp and 420 lb-ft of torque. They achieved this increase in power a couple of different ways.
While the 92.7 mm stroke length remained the same from Gen 2, the newer generation slightly bored out the engine a little further, increasing the diameter from 92.2 mm to 93 mm. Not only that, but Ford was able to increase the compression ratio of the cylinders to the combustion chamber from 11:1 to 12:1. The Gen 3 Coyote was also given a raised dome for the pistons, upping the volume from 4.451 cc to 8.411 cc. With all this, the newer engine managed to be six pounds lighter than the previous generation but maximized power.
