Can a 2005 mach 1 engine fit in a 93 ford f150?

There is no such thing as a 05 Mach1. There is an 03 and 04. It can be done with custom mounts, exhaust, wiring harness, as well as coming up with a way to adapt the front drive accessories to hook up to the truck equipment such as power steering hoses, a/c hoses, etc.
