One of my cam lobes has a groove in it (along with the rocker arm) so I am in the market for another. It has a 628 kit in it (not HRC, JE 10.5:1) and was wondering what the best performing cam would be for my application. It has an aftermarket cam in it right now but I don't know what it is because the part number engraved on it doesn't seem to match any numbers I have seen for others but it does have a W- on it so I think it might be a White Brothers. Please list any pros/cons of cams you have tried, or have heard about. I mainly ride in the Glamis dunes and want something that will work best for racing hills. I have a JE 100mm 10.5:1 piston and a Niks Pro-X rod. My head has some porting work done to the intake passage and I just got an Edelbrock pumper carb that I haven't used with it yet. What do you think would work best? Also does anyone have any other motor tips that would help me beat my friends stock '03 YZ250? Thanks
