Will too much spark advance (30 degrees+) increase the combustion chamber
temperature on my Model A engine?
Durango

The max advance with a stock distributor is 20 degrees which is 40 degrees at the crankshaft. 30 degrees at the crankshaft is only 15 degrees at the distributor and is good for low speed driving. Please explain where the 30 degrees advance is applicable to.
