main cap bolts
The inner and outer bolt heads on the main bearing caps appear to be the same size on the Coyote. On my 4.6L they are different sizes but that doesn't mean the cranks are different. I'll check to see if the main bearing inserts are interchangeable.
Edit: Coyote main journal dia. = 2.652", rod journal dia. = 2.082", 4.6L main journal dia. = 2.657", rod journal dia. = 2.086". So I can't use the Coyote crank unless I can decrease the 4.6L diameter of the main bearings by .005" and the rod bearings by .004". One way would be to purchase 4.6L .010" undersize bearings and then machine the Coyote crank journals to fit. However, I still don't know if the width of the bearings is the same. Also, the thrust bearing might be a different configuration.
MMR has a 4.75L 900 hp all forged stroker kit (crank, rods, pistons) with rings, rod and main bearings, oil pump with pickup tube, and ARP main and balancer bolts. It's currently on sale for $2000 ($300 off).
