Carb CFM recommendations

Relax dude, trying to help. The way you wrote it is "the best options I have" I took to mean you already have the carbs. That's why I said "try them all". So if you haven't bought the carb, then I don't think you listed the best options you have. I have a 770 on my 318 because it outperformed the 600 eddy and 670 I had on it, ET proven. I have less of an engine than you. Good luck :)

Yes, you are right. That was poor wording. Best options is like favorite flavor. I doubt we will agree on what is best. And in carb world, sometimes it comes down to knowing what you are comfortable working on. I am not a carb expert by any means, but have always had good success with Carter, and Eddy's are basically a new version of them. I appreciate you sharing your experience.
