It's not likely he will pass, the people who are baking this law are 'pit-phobic' crazy. I've heard of Jack Rustle Terriers, labradors, and all kinds of hounds being mistaken as pits, and thus taken from their owners and sometimes even euthanized.
Besides that, the definition of 'pit' has become so obscure that it really is hard to protect a dog in any way. If one person decides to dislike you, they can call up the pound and tell them you're hiding a pit. The people working for the pound aren't dog experts, and if they believe they're right they'll take your dog and you'll wind up in court.
How nice the dog is has nothing to do with it, it's the reason any dog lover is against BSL of any kind. They don't care one drop how nice your dog is, even if it's a therapy dog.
The only exceptions I've heard of is for the pits already living there, because in most instances they have a no sell, no import, no breeding clause writtin in.
