The box stock Ford Performance 5.0L Ti-VCT Coyote crate engine and related electronics is the best crate engine value going because this is a turnkey product with a warranty. On the dyno, void of accessories and an emissions system (catalytic converters), this crate Coyote makes more than 487 hp and more than 400 ft-lbs of torque. (Photo Courtesy Ford Performance Parts)

Top:
The Coyote’s camshafts ride directly on cylinder head journals. There are no cam bearings, just the oil wedge that the Coyote’s lubrication system provides. This design nuance is carried over from the 4.6L and 5.4L Modular engines. Here, Performance Assembly Solutions, which builds Ford Performance’s crate Coyotes, applies engine-assembly lube to cam journals during assembly.
Middle Left:
Some confusion surrounds these piston-cooling oil jets, which provide good heat transfer to the oil and carry excessive heat away, especially in boosted applications. Coyote blocks from 2011 to 2013 had them, but then Ford dropped them. In the course of 2015–2016 production, piston-cooling jets returned. Expect to see some blocks with this provision and some without.
Middle Right:
Total Engine Airflow (TEA) does a nice CNC-ported Coyote head sporting Ferrea stainless-steel valves. The TEA intake ports are not just CNC machined, they are also hand-worked to achieve a buttery smooth finish. There are no lines and ridges to cause turbulence.
Bottom:
Crankshaft endplay is checked and documented. If it doesn’t measure up to standards, the block and crank are disassembled and each is checked to find the cause. Thrust bearing thickness at the number-5 main bearing cap is how you modify endplay.
