Looking for the mechanical advance specs for this distributor. They are normally in the "Owners Manual" and list the degrees advance with the corresponding distributor RPM's. Trying to find out how they match up with the 1940 Auto-Lite model IGT 4201 distributor. For some reason, someone previously installed a 5402E distributor in my 1940 356 engine! Any suggestions where I might look to find these specs if they are not in the 1954 manual?

The later dist probably advance "faster"and "further", probably not a
bad thing, today's fuels are a little higher octane than average regular
then. Is it giving any problems? Like firing back against the starter or
pinging under load?

Bill, from my 1959 Motors Auto Repair Manual.
