Just rebuilt a Coyote motor for a good friend of mine that popped cylinder 8 with 7000 miles on the car. Car was running great and making loads of power. He did a pull and when he let off it threw a CEL. Code was p0308 misfire cylinder 8. Here's the carnage.

Got the motor apart and sent to the machine shop for balance, hone with tq plates and washing

Got the block and rotating assembly back and the fun began. We are local to MMR and they were a great help to us. We used MMR(Manley) forged 10:1 pistons and rods. Billet oil gear and timing gear. Clevite rod and main bearings. All seals were changed as well. MMR secondary tensioner, head cooling mod and oil squirter block offs. Total seal rings gapped at .024 top .024 second and .018 oil retaining. Upgraded timing chains and ARP head studs. The valves in cylinder 8 were also replaced.
