anyone looking for this 69 340 block?

Do you have any idea what kind of car this engine came out of? With the B just before the build number it shows that this engine came from Hamtramk Mich. where the Barracudas were built. I have been looking for my old Barracuda for a long time and was wondering if this engine came from my car? How far from Warner Robins are you? Do you know if this engine was in a car with a 4 speed or Auto transmission?
