Advancing timing...
Guys when I advanced my truck from 10* to 15* btdc I wasn't getting any pinging at idle, but when I was putting the truck under a load the truck was pinging. Is there anyway of advancing the timing just right where you don't have to drive the truck on the highway to put the engine under a load? I even powerbraked in the driveway with the timing at 15* and it didn't ping you think that would have been a load for the engine? What is the best way to accurately time an engine besides putting a light on it? You should hear pinging when just idling right?

It will be very unlikely that the engine will ever ping at idle. You have to load the engine to have any idea of whether or not it is going to ping. I would have thought you would notice while power braking, but if it only pings on the highway, then that's where you need to check. Make sure that it doesn't ping where you know it is likely to ping, if that makes any sense.
