A typical Stronberg 97 is rated at 150cfm's and holly 94s are rated at 162cfm's?
So any combination of duel carbs is going to be way over the requirement of any but the wildest modified flathead.......? What gives???

Any more than two carbs is strictly for looks and/or bragging rights! "Oh look! His engine has three carbs! It's got to be faster than that lowly flathead with only two carbs! Hey, here's one with four carbs. More is always better, right?"
