I know my engine isn't as radical, but it is a solid roller build that favors higher RPM (up to about 7k). It's completely drivable at low speeds. As Brent says, it just doesn't like to cruise at less than 2k RPM (not a problem). One of the things I like about this type of engine is that it is relatively tame and controllable at lower RPMs, but you can get the power when you need it.
