carb. ID ?

trying to find out if the carb. on my '75 F100 4X4 is the correct one. the tag on the firewall says it is a 360, i was told it is a 390 when i purchased it ($300
). i still havent pulled a plug to check the stroke yet. anyway, the carb. on it is a 4 bbl and someone remarked it looks like a car carb. not a truck carb. number stamped on the carb. is D3AF-VA, which by doing some research here is a '73 model carb., but that is about all i can find. anyone able to provide me with some insight? Carquest is able to get me a kit for it so that is good. just basically looking to find out if it is a factory carb. for my truck or not.thanks
Aaron
