Where does the trend towards aluminum fit in with the quench issue.
Aluminum is a better thermal conductor than iron, so the “quench” portion of the quench/squish process is just more effective since more heat is pulled from the chamber into the cooling system.
In most racing situations, the lighter weight of the aluminum is just another added bonus.
I added another link in that earlier post that discusses the differences in quench/squish.
