I just installed my new comp cam 285 extreme energy high lift hydraulic in my freshly built 451,here,s the problem the paperwork i got with the cam states that comp grinds these cams with 4 degrees advance for optimum street use,so anyway i line the dots up perfectly inline and centreline it in and it goes in at a 102 degree centreline ,the intake centreline for this cam is 106 as stated on the cam sheet i got from comp,so at 102 with the dots lined up is in 4 degrees advance ,so i reinstall it retarding it 4 degrees on the cam sprocket,recentreline it in and of course it comes in at 106,perfect,so now my centreline is to spec as to the cam card,but i miss out on the 4 degees advance that comp grind into them when the dots are lined up,this is bizarre,do i put it in at 102 degree with 4 degree advance or do i put it in at the correct 106 with 4 degree retard,has anyone else had this dilemma,my motor is a brand new 451 with compression at 10.25 to 1 it,ll have a 4500 converter i dont want it to overheat or ping,i currently have the cam in at 106 centreline,will this be fine,am i going to lose power off the line???????????????????????????????????? Matty!!!!!
