I see where the AC Delco cam bolt list ±2.5° of adjustment whereas the MOOG list ±1.125° of adjustment; AC Delco ones come individually; MOOG come as a pair.

Is the MOOG adjustment range enough or is the additional range of the AC Delco required?

I could probably answer my own question by looking at what setting the cam bolts are currently at...just not sure if they are correct or not.

Anyways thought I would ask.
