Rebuild or Replace 850 TQ for a Mild 340?

I agree with buying a kit and rebuilding the carb. Lots of good stuff on YouTube. I do have one question, though. In your original post you said that you had a Mild 340 and an 850 CFM Carb. Different people have different ideas of what a mild 340 is. I was just wondering if 850 CFM is a bit much for a mild 340. I have what I would call a moderately modified 340. It is at 375 HP. A 750 CFM Edelbrock works great on it. It is JUST a question. I don't know enough that much about matching carb CFM to engine size and HP level.
