Yes, cool. The more barrels you have, the more evenly the fuel is metered out to the cylinders. With a 2 or 4 barrel carb, the inner cylinders closer to the carb can suck a little more fuel then the outer ones where the fuel mix has to travel farther. Even with two four barrels, there is a chamber where the fuel air charge mixes before entering the cylinders. The old 8 stack, modern tuned port, or 8 webers are the only ones that give an equally metered charge to each cylinder.
Thanks. Now I have some understanding of the actual usefulness of multiple carbs in terms of performance. I had always assumed it had as much to do with the ‘cool factor’ as performance.
