The picture of the VIN plate is not too clear, but it appears that the tip of the Pentastar (5th digit in the VIN) points to an "F". If this is correct, the car is an original 318 2-Barrel, which is consistent with the "Barracuda" badge on the rear of the car.
What is really cool about the numbers on a Mopar is that the 5th digit tells what the original motor was. Good for folks wanting to verify the original engine, bad for slimey folks doing a clone and trying to pass it off as original. That is unless somebody is into fabricating VIN tags, which to me is almost as bad as child molesting (and illegal). Unlike old Chevys and Corvettes, where the VIN tells nothing about the car except the sequence it was built. Plenty of bogus 67 Corvettes out there with 427 engines. Much tougher to forge a Mopar.
These E-bodies (particularly 70's and MORE particularly 71's) are drying up- if you are thinking about buying one in reasonable shape, stop thinking and buy it. It will be worth a lot more in a few years.
