Montana_highboy is correct. The ONLY way to know what you have is to measure the stroke.
With Fords there is no way you can use casting numbers to determine what engine you have. The same casting numbers were used for years and on several different displacement engines.
If the fourth character of the VIN is "Y" the truck originally came with a 360, if it's an "H" then it came with a 390.
Just a note, a lot of 360's become 390's on sale day.
