Re: timing a small block?
Depends.. What kind of ignition and cam you runnin?
If the cam is more than stock, then share with us the grind info or cam model. There are a whole lot of other factors in play here with your question, so get ready to hear a lot of questions. Since, your Q is so open ended.

Re: timing a small block?
8 to 12 degrees initial is a good starting point. If your HEI has lighter springs set total mechanical around 32 degrees to be safe. with vacuum hooked up and 2500 RPM I like around 45 degrees to help with good fuel mileage. Vacuum advance hooked to PORTED vacuum on carb.
