I am looking to replace my cam. I have the HotCam now and have been looking at the CC306 and XE230/236 my question is between the grinds.


CC306 IN EX XE230/236 IN EX
DUR @ .006 290 307 282 288
DUR @ .050 230 244 230 236

Now if you look at the CC305 or the HOTCAM
DUR @ .006 276 290 279 287
DUR @ .050 220 230 218 228

So if you look at the duration at .006 the CC305 is bigger on the exhaust then the XE230/236 and the HotCam is not much smaller then the XE230/236. I searched in LT1 Tech and Advance Tech, I guess someone needs to explain the XE grinds to me. Thanks

 

that means the XE230/236 has faster ramp rates, i.e. it takes fewer degrees to go from .006 lift to .05 lift. Better for power worse for valvetrain.
