Mysterious 1964 dart rag top????

sounds a lil high for a rough car. The engine size is on the driver side of the block right by all the freeze plugs, rearward of the motor mount. It also could be a 3 spd sick instead of a 4 spd. I think the /6 cars came with 3 spd. There was a guy around here with a really rusty one that ran with a 318 3 spd and I didnt even want to give him $800. He sold it on ebay for over $2000. Its crazy.
