Supercharged Slant Six

Very cool. Couple questions. What fuel? Are you using the Holley to control timing? (You could probably idle much cleaner with more initial and still limit total timing). And do you have any plans on dynoing it or making a pass at a drag strip?
Running premium fuel, 93 octane. Sometimes i run up to 10 degrees at idle. Running a Petronix in the stock distributor with lighter springs, and a Accel super coil with Taylor wires. I was concerned about the spark breaking down under boost and have to go with an MSD, but so far it does not miss a beat. I do not have a timing control.
