I have mine set to .044 but then again I'm carbed and I don't take any chances even though I'm running a wet kit I ran 105 octane to insure no detonation would occur and I have a total advance curve between 34 to 36 degrees on my msd dizzy!!! I was lazy the first time out and didn't even bother backing the timing off...however amazingly enough the car ran well with no detonation and or leaning outor fuel starvation with fuel pressure set at 5.5 psi
