nice you got lucky, a 3.73 v10 is rare.. most I have seen were 4.33.

Take the time to degrease and prime and paint that engine compartment now. It will be Much easier to do and lots of access etc.. looks like you have a garage to work in so that makes it much easier! Try to separate the harness and mark what the wiring was for.. tip for masking so you don't paint the wires etc..use aluminum foil wrapped around the wires / parts.. its quick and easy..
