Actually, the diameter could be enlarged, but it would have to be funneled down to meet the blade..so technically the size would change.

that is incorrect, you cannot go over the size of the blade,,you can do whatever you want to the opening,,but when your down to the blade area (the part that counts and is measured) its going to remain the same,,if you go over, your blade will not keep air from coming in.

Well, We are both right and wrong. Some people go by the outside opening...even Ford.... Their Ford Racing 70mm throttle bodies have a 70mm opening...but narrow down to 67mm.

should only be measured on the blade area,,the front of a stocker is huge compared to where the blade sits,,same with all TB's

FAST 90's and 92"s,,,blade area measurements

etc
i dont know of anyone who would measure the front opening,,that dosnt make any sense,,which is why i do understand why FORD would do it.
