All I can say is..If you see the car..you will want the car!! Not numbers matching,but 340 is a 1970,beautiful manifolds,and new hurst shifter box,rods,and original hurst shifter included,I'll even throw in a 1970 mint grille! If it doesn't sell soon it will be put up for sale again after winter for more$$$ I have lots of money in this Duster,and no way could you even come close to building one for this kind of money!
