Thats what I understood and the main reason I chose the 4-7 / 3-2 swap for my build. I was not sold the theory of additional power by anyone... Just smoother running through the RPM range taking stress of the rotating assembly / block trying to hold it all together.
I was originally building a Cast iron block... have sense gone with an aftermarket block and the harmonics are really not as much as a concern as with the factory block. Already have the came now.
