what is a running 318 worth

nothing! you better send it to postage paid right away so i can put it to use lol. seriously though it depends on if someone really needs it or not i have one that was completely gone through bored 30 over and has $2500 in parts in it that i built for someone and they screwed me on it . sold the car and told me he didnt want it and wasnt paying for the parts .
i tried selling it a few times and the 3rd attempt i had a guy come out i fired it on the stand for him he offered $300 i laughed and asked him why he even bothered to waste my time or his when he already looked through the stack of receipts .
I said the heck with it and took the ad down ill keep it for my car when i get it done .
I see them once in a while on craigslist for $200 around here and they sit there forever , but cl around here is chevy land . could build any chevy for a few hundred bucks with cl parts . very few mopars or mopar parts listed .
