grumpin Posted November 30, 2021 Share Posted November 30, 2021 As I stated earlier in this thread, I really like my Edlebrock 1406. It's been a great carb, easy to work on, reliable, no issues. As the AVS version has annular discharge, I wondered if my 1406 could be converted to annular discharge. In a web search that lead me down many paths, not finding what I was looking for, I did stumble on an interesting option in the Summit M2008. This was originally developed by Holley but then dumped for a few reasons and then picked up by Summit and modified. The reviews on this carb are very good and it has a lot of nice things about it including annular discharge. Yes, it still has the old power valve for which many complain about, but for some that is just not an issue. Based off what I read, if I were looking at purchasing a new 600 CFM carb, I might just take a chance on this. https://www.summitracing.com/parts/sum-m08600vs Just something I looked up, because I was concerned about the Holley power valve issues. Holley carbs built after 1992 have the check valve.
