I suppose this topic has been done to death, but here goes. Recently put a new motor in my XH ute. Balanced, EL XR 6 cam and head. After we got it running, took it to a Ford dealer who set the base timing to zero.
Now when I put a timing light on it, the mark is opposite what I guess is about 7 degrees. Apparently the computer adjusts the timing to suit conditions. I use BP ultimate fuel. Can I adjust the timing a few degrees advance by rotating the distributor to gain some more performance, or should I go back to Ford and get them to do it ? Is there an easy way to to set the base timing ? The shop manual says a bit about shorting out a couple of pins in the plug under the dash, but we are a bit loathe to fiddle with that .
