It's been awhile since I studied the Pituophis family of snakes (which includes gopher snakes, bullsnakes, and pine snakes). I did quite a bit of research into them though, when I was learning how to care for our gopher. Unfortunately, my memory leaks like a rusty bucket, so I'll have to find my old research material to get you more concrete details.
Bullsnakes are generally considered to be a subspecies of the gopher snake (Pituophis catenifer). Their scientific name is Pituophis catenifer sayi, or P.c.sayi. They actually come in many different locales and their sizes vary considerably from one part of the country to the next. Their color also varies a lot, depending on where they're from. Some locales can reach sizes up to 6'-8' in length, if I remember correctly, and have the girth of a soda can.
I'll look for my old info that I've stored up and see what I can find. In the meantime, you can google the scientific name and probably find lots of info yourself. Also look up Cherryville Farms. They are a highly reputable breeder of Pituophis snakes.
