75mm...its just that you port the housing infront of the blade out to make it a true 75mm were before its a 75mm blade with a 72mm hole to breath through in front of it

Tb Thanks, I guess I am going to have mine ported. I was torn between a new edelbrock TB and having mine ported. I have decided to get mine ported and save the $$ that i would spend on a Edelbrock. I was just curious as to if the porting made the size close to 80mm then I would go with a new TB.
