I can't tell you what timing to run, it depends on your engine mods, porting, etc. I can tell ya that the timing issues are a fairly common question and can be found by searching "timing" in the first gen. section.

You also might get a better answer by asking in the "racing" section, where they may be more familiar with that type of setup.

 

You'll need to get your pulley properly marked for #1 TDC & degrees from there before you can do much else, so I'd research "finding TDC" while you're at it.
