I don't think a 70mm would hurt your performance at all, I think it would help out. 75mm is pretty big for a N/A 306. Throttle body's aren't cheap though we all know that, so I would try and make yours work. The Holley is more expensive too, with it being like $229-39?+TB spacer at like $90ish?, I have no experience with the Holley TB though, so I can't tell you that it wouldn't do the same thing. I've never heard any complaints though, & it's polished. Why don't you give BBK/Edelbrock a call, and see what they think about the problem? Then if you can't get it fixed, & they can't tell you what the deal is, sell it, and try out a Holley.
