I am getting ready to pick my cam. This cam is going to be 537/564 on 1.6 roller rockers. Duration is going to be 232/240 and on a 114 LSA. I need to find a decent advertised duration somewhere between the CC306 and the XE grinds. I dont want the easy ramps of the CC306 but not as radical as the XE cams. Anyone got an idea?

 

With this type of thing you are generally limited to picking "off the shelf" lobes, so to speak. So the ramp rate is tied in with the lobe.
