Re: roller bearing for cam
Most roller bearings are grease lubricated (ie: wheel bearings).
The thing is to go from a plain bearing, such as the type in most engines, to a roller bearing, you require more space for the bearing to fit. That can be done by making the diameter of the cam bearing lobes smaller (making them weaker) or by machining the bearing seat out. To get any real benefit from a roller bearing, it needs to be large to handle the loads but on it - which could be an extra 10mm larger then a plain bearing. This ofcourse is where the cost comes into it.
Unless u want big power, such as near 800hp, then i cant see the point really.
