Ten degrees BTDC is a nice place to start. We're just trying to get the car to idle nicely, and not leak, then we'll graduate to having it drive nicely. But, since you mentioned timing, of course your total "all in" timing is what's important. I think you have aluminum heads, like mine, and my engine runs best with 35 degrees total advance. So, with my MSD distributor, I have the 25 degree bushing installed along with ten degrees initial timing to give me that total of 35. Ten degrees initial puts less of a load on your starter (which you just might benefit from). I use the light silver and blue spring combination to achieve the following curve. Notice how the advance comes in. This works very well for me and has for many years.
