My 78 came with the 2700VV peice of ____ and I'm coming up on time to get it smogged again. I have been told that I can switch to the 2150 model and still be smog legal (visual). I have also heard that a few of you have been running Holley 2-bbls and passing smog. Is this true is the Holley legal or the tech just sees the 2-bbl and doesn't question it? What are my options I don't like the VV carb and want to replace it.
