what do you think its worth?

I think it's probably worth a little more than that since you have the fender tag to show its a real 340 4 speed car, but, regardless you'll get more parting it out. Looks like a fairly solid car though other than the inner fenders being removed, parting it would be a shame. Too bad the matching numbers engine/trans is gone.
yeah - I was being a little facetious...
