Thanks Lovehamr, good advice and one I'll take if I don't find what I want "mostly" pre-built. PS - Love your Avatar, took me forever to read your post because I kept getting distracted :-)
Good point JeffNolan, If I do go with a Coyote I'd have to have it professionally installed because it's way out of my knowledge base. But the scuttle I've heard on the Coyote is it's more like a modern car;
oil, plugs, filter but otherwise mostly forget it. Yes, I was thinking the 550 HP range would be a good sweet spot of plenty but not to to much, and still easily achieved.
Mln385, I'll have to find out if that's still the case.
