27 degrees with no retard in the box.
Find the happy point for the timing (less than 27 degrees) or computer retarded for the
different boost levels. You will find it very hard to stay at 7-8 psi once you are driving the car, LOL!
John Clegg's 64 Pontiac Race Car used a simple "box" with timing pulled in 3 degree steps. You should be able to do much better with your electronic timing capability.
11.5 is a great Air/Fuel ratio to get dialed in initially.
