Here are three links to the stock info that might help. Link one
The stock timing without the vacuum advance connected is 5 degrees BTDC. This should be able to be safely increased to at least 12 degrees BTDC for additional performance without any pinging.
Looking at the HP RPM values and the torque RPM values, I would still suggest the all-in between 2500-3000 RPM for the best street performance.
That engine (even in stock configuration) should be great for bottom end torque. Compression is high and will require a higher octane gas. ENJOY!!!
