What is the best adjustment for engine timing?
Is it exactly at 0, or do you like to set it a little before or after that?
And I'm just talking about regular daily driving -- in city, with occasional freeway stretches. I'm not towing, I'm not off-roading.
I have a 1987-1995 GM 350 5.7 TBI on a K20 (3/4 ton suburban) with 35 inch tires.
