What is a 67 TNT 440 worth?

2 years ago, I sold a 440 from a 71 imperial that had not run in 15 years. It was complete from the air cleaner to the drain plug and from the fan blades to the flex plate - all brackets/pulleys/accessories included. I got $1000 for it. Like moper said - it all depends on what someone is willing to pay for it....
