correct a/f

I know that every car is different but since i dont have acces to a dyno to find out my best a/f for power.
what kind of a/f should a 383 with 10.1 compression run n/a.

My dyno is just 10 minutes north of you in rohnert park;)

Look for 13.1:1 for best power, maybe you will need to drop to 12.8:1 to ward off detonation with our crappy cali 91 octane.

how much do you charge to dyno a car. Whats ur shop name?

Check your PM.
