Actually, there is no comparison with anybody else. Rock solid and proven. S&S partnership resulted in having truckloads of cash and other resources to develop this. Of course, there are a few options where you can add more power (like cam and compression) but it makes a ***** load of usable street power as it is.

They engineered it from the beginning as street engine based on the geometry of the current HD twin cam, which is very good btw. The biggest difference is the cam chest is offset to allow for the large bore and the oiling system is designed to handle that displacement efficiently.

Lastly, the B-2 heads have large, raised high volume ports, "D" to almost oval shape to move the amount of air that engine requires @6500+ RPM's

Assembled and out the door minus induction / ignition is @$10K+
