Doing the final H/W plumbing on my 261 with the Offy intake and dual carbs bought from Tom Langdon. He states that you can try coming off one carb vacuum tip to the distributor vac advance or you can try coming from the full Offy intake port. Since I'm doing this in stainless steel, I really only want to do it once. What have my fellow SB's found to work the best? Off one carb base or off the Offy? Thanks!
