That v10 would be awesome in little blue!!!
Its much cheaper and easier to go 6.0 LS SWAP. All the chevy to ford transmission adapters already exist. Tons of easy and cheap engine control options. Its all just plastic, steel and aluminum guys. Its all engineered by the same guys who get hired at one manufacturer, then cannabalized over to the other. If Ford had an engine platform as popular as the Gen 1 to Gen 4 small block chevy, everyone would swap those fords into chevys.
Little blue will remain ford, for now. But I am a car guy, not just a ford guy. You can pick up a 5.3 liter LS for $500 with factory accessories and ecu.
