Summary Thoughts The Twin Cam is an excellent engine and includes several refinements over the Evolution, including stouter engine components and the potential for increased displacement. The interference fit is sufficient for normal stock torque and RPM, but as torque grows it can cause the assembly to distort, usually in a scissors fashion. anyone offering a option to the SE LATE MODEL COMPS? However, I'd also recommend it if you ride near redline at all, or on a regular basis. If those parts need replacing, it is a wise idea to replace them with the 2007-later (2006-later for Dynas) high-volume oil pump and a compatible cam support plate. This is why some people appear bright until you hear them speak.
