Heres a somewhat related question about cam timing...
If I have an adjustable timing chain with multiple keyways on the crankshaft gear, and they are marked 0, +1, +2, +3, -1, -2, -3, etc...
Lets say I have a lobe separation angle of 106*
If I set the timing gear so that it is in the +2 slot, does that mean I am advancing the camshaft 2 degrees so that its now 104* or does that mean that I am adding 2 degrees to the 106* number? 106+2=108?
Lobe seperation angle is not the installed centerline. Lobe sep angle is ground into the cam and cannot be changed. The installed centerline is where the cam grinder reccomends to put the intake centerline for best performannce. Ron
