L&R Engines in Santa Fe Springs, California, was the shop we chose to build our Coyote engine. Ahead of our build session, they honed our block .010-inch over, lightly decked the heads, and checked the main’s align hone. Even with nearly 100,000 miles on the clock, our F150 core was in great shape.
I’ve personally followed along with six Coyote engine builds and they have all used stock diameter main bearings, though King does offer over and undersized.
The new and balanced BOSS 302 crankshaft is installed and the ARP nuts are torqued to spec.
Coyote engines feature extremely robust six-bolt mains. ARP includes the side bolts as part of their main stud kit.
Our JE Pistons hung on K1 Technologies’ H-Beam rods. The K1 rods are a great value for a forged 4340 connecting rod and we’ve seen them make over 1,000 horsepower in a Coyote configuration.
Our JE Pistons feature a symmetrical skirt design that has a relief for the factory oil squirter, though we didn’t use them for our build. We started with their 11:1 PN 314420 and reduced the compression to 10.5:1. With our block and head decking we ended up right back at 11:1 where we wanted to be.
