What's your budget?

So a friend is going to be fielding a spec car next year he has purchased a great car that has been run in spec but it was missing the engine. He came to me and asked if I would help him put together his engine. We are picking up a core and going from there. So any secrets you guys in the know are willing to share would be appreciated? Help?
