Speakingb of Saturn V's,here's an interesting article about a recent project to get re-acquainted with the Rocketdyne F-1 engine.
If you haven't read it it is worth getting hold of "Apollo" by Murray and Cox, there's a good account in there of the lengths that were gone to to try and solve the combustion instability problem (which would have been a project stopper if not fixed) mentioned in the article.
