I'm currently looking at a 1973 Mustang Grande for sale at a local classic Mustang dealership. The car deffinantly needs some body work, a new point job, and a new passenger seat, but for $1700 we think it's a pretty good deal. Alright now back to the original question. The car has a 351c in it that still runs pretty strong, and I was just wondering how much the engine could possibly be worth. I'm not sure if it's the original engine or not but if there if anybody could have any idea or could help me out it would be appreciated. Oh yeah and by the way if this topic isn't on the right board, this is my first post and I wasn't exactly sure if this was the right board or not.
