Are all the V-6s that noisy under the hood?

Smart phones don't do a very good job of recording engine and exhaust sounds. I did a couple recordings that sounded nothing like the actual engine and exhaust. You would have thought all the lifters were bad and the exhaust had leaks!

It just seems strange they can supply enough air volume to those torque monsters through one little carb.

The 478 specifications show it made peak torque at 1400 RPM and peak horsepower at 3200 RPM. At those engine speeds, it doesn't consume much air!
