It's a pretty cool old cuda. It has been apart for ten years and prior to that had seen a pretty tough life. Like I said, this trans was nasty and had dirt stuck to it collected while Nixon was still in office. The original block was history when I got the car. It had a '68 block in it. I do not know what happened to the original... grenaded or broken somehow. Prior to me owning this car it was in thrashed, survivor condition having been through a shot to the front of it that required a lot of work to correct. I would be willing to say that it was never in a state that would drive a previous owner to screw with the numbers. No indication on this car show that it was ever treated anything other than harshly. It had the '68 340 block for a good long time. Like I said, the car had never been treated well. Not well enough to warrant going to this extent. It just does not add up for this car.
