 ''' CAMSHAFT '''
-The camshaft has terrible oddities. I'm a  metric guy and have measured up to .52 mm (0.02 in) differences in lobe lift vs. base circle from one lobe to the next. Also the base circles differed by 0.4 mm (0.015 in). I hope that CompCams or Crane deliver the precision they advertise. (BTW measured not only where the roller of the lifter runs but also at the edges of the cam.
+The camshaft has measured differences between the intake and exhaust cams of up to .52 mm (0.02 in) differences in lobe lift vs. base circle from one lobe to the next. Also the base circles differed by 0.4 mm (0.015 in). The COMPCams cam has an equal base circle and lobe lift on intake and exhaust. (BTW measured not only where the roller of the lifter runs but also at the edges of the cam.
+Also make sure you understand the various lobes as they are in a specific order of intake and exhaust lobes.
+The bearings are pressed into the block and have an oil hole each which needs to be aligned properly with the blocks delivery holes.
