That lincoln puller fan recommended above moves a TON of air. You can buy them new, as well...try rockauto. If you have room for it, that would be a great option. I used one on my truck; it's amazing.
460's should not run hot. A friend runs an

oil path because he couldn't get it up to temperature. This was in a Superformance.
