Timing steps please

I know this has probably been beaten to death but I just got my sbc 355 running again thanks to you guys. I know it should be timed at 36 degrees. What are the steps to achieve this? It has a hei with vacuum advanced which I don't really care to use. What is total timing and initial? Thanks fellas.

Wow. Lots to read but still confused. How do I know the difference between total and initial? Do I time it to 14ish degrees and then rev it up a little and watch how much it advances mechanically,then add the two to get my total?

Remove the vacuum advance hose and cap off where it was connected.

Make sure the idle is around 700ish rpm.

Set initial timing from here. Say 10-12* to start.

As you increase engine speed make sure the mechanical weights in the distributor are advancing the spark. This should add around 20-24*

After all that's done hook up the vac can and check operation of that as well.

Any clearer????

If you are not going to use the vacuum advance, plug it off and just turn the dist. until you have 36* at 3,000 rpm. This will let the initial fall wherever it wants to. In other words just set the total and the initial will take care of itself. You may have to play around with the total a bit, give or take a few degrees to keep her from detonating.
