As I try to set my timing for the first time on my carbuerated 94' 5.0, I am trying to know was much as I can before I go and pick up a gun and attempt to set the timing. I just installed the explorer serpentine conversion and had a complete top end rebuild- I have a mallory unilite comp 9000 breakless dizzy.
I found this MSD video of a small block chevy on youtube which brought up some questions as they apply to my engine.

In the video they talk about 3 important parameters or a range that the timing should be set, and I have no idea the range.
The parameters mentioned in the video are all advanced before TDC:
1. Initial timing setting (for idle) for small block chevy is 12 degrees
2. Total timing (highest advance for higher RPM)
3. Ignition Timing Mechanical Advance (curve; rate of timing advance)
So my questions are:
1. To find the initial, I need to find TDC. When I had the valve covers off I had it marked slightly after 0 degrees TDC (retarded). Did I screw that up? What is a common TDC to start?
2. How do I figure out where the total timing or the highest degree of advance should be?
3. On my mechanical advance dizzy that was already in the motor, does it automatically set the curve itself?
Please bare with me on my ignorance, but this is how I learn.
