A cam ground with a 110 lobe seperation angle will in most cases be installed 4* advanced , this puts the intake centre line @ 106* & the exhaust centre line @ 114* , some say the reason for this is to allow for chain stretch , the cam card will say @ what CL the cam should be installed (if 112 lsa then they want it installed @ 108), is this what you're asking?
