Need help choosing a junkyard engine

Well the 74 had the key in the ignition but the carb was not bolted down anymore. The 67 seemed ready to go but there wasnt a key. Could somebody give a crash course in hot wiring the 67? I'd really like to hear it run before I take the time to pull it.
What exactly is different between the 67 and 74 cranks? What would I need to do to make the 74 work if I go that route?
I believe I read something about the post 68 heads being slightly better. Is this true? If so should I yank the head off of something else. There is a 1980 road runner with a slant in it as well. would this have a better flowing intake/exhaust manifold or are they all about the same?

Take your '63 Ignition switch with you and plug it into the '67 dash harness to fire it up. Use the '67 carb on the '74 if you have too....it'll bolt on. Bring some gas, water, battery, oil, and have at it! The '72 and later heads came with induction hardened valve seats. Other than that, they're all decent castings. The '75 and newer have the advantage of external spark plugs so there won't be any leaky plug tube seals but the later heads seem to have more crack problems...not a lot more, but a little....probably because they run those engines hotter for smog reasons.
