My Dart Swinger Project!
I know you are invested in a rebuild in labor at this point but if it were me in your situation, I would go for something like Dicer posted. It's going to likely save you money for sure in the short run and gets you on the road a lot quicker. Then way when you've got some cash saved up you can tear back into the 360 or the 318 and do a slow rebuild while you're enjoying the running Dart.
If it is already pulled take a compression tester and a battery with you to make sure that's good.
Just my two cents:
