I think the 351W to a 66 Mustang would be just about a 'bolt-in' deal, I'd use dropped engine monuts so that the air cleaner stays under the hood, maybe some shorty headers as the deck of the 351 is about an inch taller and has been known to make for some problems.
I think Hedman has those headers right off the shelf....

Guys I'll tell you you need to start your own threads with questions like that, not jack this one. I am interested in seeing how the 390 swap plays out, so don't want to see the thread veer off course

Thank you, I'm searching everywhere trying to find the motor mounts and headers, thats the only things Im really missing

If you don't have any luck you can always fabricate your own. It'd be a pain to get everything right, but then it opens a way for others to do the swap.

True, I am not much of a fabricator, but I can ask around a few of my friends may be capable
