That's a huge cam, with an advertised duration of 311*. You'll need a lot of initial timing, like 18-20*.
Set base timing at 18*. Then hook up a vacuum gauge to the manifold port. Adjust timing until you get the best vacuum.
A SBF seems to make best power around 36* total timing, all in by 2,500-3,000 rpm's. So adjust your mechanical advance to get there.
Vacuum advance is a good idea, even for a big cam like that. On light throttle cruise, you'll want the timing to advance anywhere from 4-10*. The engine will run cooler and be more efficient.
