When adding timing past peak torque, how much and how fast should it come in?
Lets just use my engine for example, since I know it and its a common combination. Stock pistons, 2802 cam, 62 heads, RPM intake, 93 octane.
My combination likes 29 degrees at 3000, 32 degrees at about 3300 RPM at WOT. Does it make sense to add more timing later, like 34* at 3500 RPM? Should I add another 1 or 2 degrees at 4200 RPM? This is possible with the PI distributor.
What is the sign you've added too much timing beyond peak torque? Is it reduced power, surging, pepper on the plugs or what?
