distributor centrifugal advance 35 supercharged Auburn

Distributor machine says my dist. is advanced 5.5 at 1800 RPM and 7 degrees at 2000 RPM. Car runs good so I left it there. That was 4000 miles ago. Just another opinion. Looks like you will have to try it for our self.

It has been my observation that even though the book calls out for 5.5 degrees @ 2200 rpm the stiffness of the stock springs do not allow that. As I recall it would barely advance 2 degrees at 5000 rpm. Three IGH4027's were tested all were identical. Just for grins, we replaced the springs from of an IGP4002; the advance curve changed significantly. When we put the distributor in the car it ran lousy. The stiff IGH4027 springs were replaced and remain there today.

I asked an old-time engine guy about this, and he said that there wouldn't be much difference if you changed the spring tension on these cars. He did show me a catalogue with different springs with varying tensions and they are designated by the color of the spring...

Hi Mark, the advancement can be calibrated by changing spring tension and while using a distributor machine; my request is if there is a guild line for the spring calibration...

Hi, Lee: I didn't think there was a setting. The weights are fixed on single posts. The spring tension can be changed by installing different spring types, however.

Hi folks,
anyone know the best setting for the distributor mechanical centrifugal advance for a '35 supercharged Auburn...I've looked in motor manuals and they either don't say anything or seem off in their info...Lee
