I may have an opportunity to purchase a 1967 Shelby. I don't know much about the car yet, other than it needs to be restored (but is in restorable condition) and has been sitting for over 20 years. I was told it has one of only a few (7-9 he thought) racing engines in it. Does anybody know what type of engine this would be? I know I need to get the VIN number but I won't be able to go see it for a week or two. Also, any rough idea what this car is worth? Thanks
