65 Barracuda with factory 318??

I have spoken to a guy who tells me he has a 1965 Barracuda with an original 318 engine in it. He says it was his father's car and was ordered from the factory that way, with a 4-speed on the floor no less.

Does anyone know if this was in fact a possiblity to order the 65 Barracuda with this engine? I have never seen, heard of, or read about any first generation Barracudas being available from the factory with a special order 318.

If it is possible, how would I distinguish it from a 273 (such as on my 66 Barracuda)? Please help! :banghead:
