..getting closer to paint..
What color are you going to paint it?
You couldn't be blamed for going corporate blue. I personally went with Ford engine gray (including aluminum heads and intake), just like the 5.0 was when it was new. I think it's really cool and clean looking, but some people think I'm crazy. Your milage may vary.
Mine was from an 85 GT, which had vintage looking black ribbed "Powered By Ford" valve covers, so I stuck with those. Not the best photo of the paint, but you get the idea:
Also in this photo, You'll notice my cobbled-together upper radiator hose. It has two splices hidden by the ribbed plastic. Both a stock 66 hose and a stock 5.0 hose chopped up to clear the belt tensioner and still end up at the right place on the radiator. I have some metal pipe in the joints. Works great, never leaks.
Edit: also, if you're planning on a new radiator, you can just get one with the lower hose connection on the correct (driver) side, but if you intend to keep the stock radiator, I have a nice Ron Morris swap tube/hose with silicone ends for sale if you're interested. I ran it for years with no issues, but when my radiator sprang a leak, I went ahead and got a new one with the hose on the drivers side and went poking through autozone's hoses. I think I ended up with a shortened Chevy truck hose for the bottom one.
