What's It Worth?

I need some input from you guys. I don't know much about the price of B bodies and found this car in storage. The guy said make me an offer and I have no idea what it is worth. The guy said it needs a carb cause it starts and stalls, but we know its the resistor!!!! Does anyone know prices of these things and would you make a roadrunner clone or keep it original as it appears to have 70K original miles on it. Might be a sin not to keep it original, Thansk for any input Walt
