I am asking if any member has data (tables or graphs) pertaining to the distributor's spark advance vs. the distributor's RPM for the `29 La Salle? That info is requested to install the correct springs for the distributor's centrifugal advance weights. (I suspect, but don't know, that the data for the `29 Cadillac's V-8 would be similar enough to use).
Go to this site:

Look for the 1930 Cadillac information kit. Among the documents is a data book with a graph that charts engine RPM against horsepower and spark advance. Maybe that will help you.

Thanks for a place to start. I'll take a look.
