I don't even think that was an argument. What was said was, that normally, hot rod engines make WAY more than enough power to warrant a crank driven fan. And if that's not true with your build, then you need to stop wussy builds.
Why would you want to give up all that power though? You can spend $100-200 and set up an electric fan, and you get all that power back. A lot of bang for your buck
