Split Duration Cams
Do split duration cams improve the powerband for our cars? The goal is maintaining midrange, while keeping up top end power. This is for overrev mostly, including no loss of low end torque.

Here you can see professional Long Tube Headers on the LS6. Notice the irregular torque curve, which implements more top-end than midrange, including carrying revs past the factory 6500 rpm. This cam is the stock ls6 cam, specifications 204/218 with 117.5 LSA.

Here is another specification that utilizes a better curve for the implementation. As you can see, low end / midrange torque is greatly improved with better power on the upper end as well.

For best analysis, you have to check two variables, one is the power of the cam in relation to the engine, the other is adjustability corresponding to the driving. For example, stock cams can be advanced or retarded based on the application, without having to switch out cams. This will modify the curve, depending on the motor, for the implementation. Instead custom cams can be specified as required, thus there's no necessity for advances or retards.
