Melonized Distributor Gear
GM requires the use of a melonized distributor gear with steel roller cams. What exactly is "melonized"? Is this a surface treatment for a hardened steel gear?

You have to run softer metal on the easy to replace dist gear. Melonized is softened iron. I use the comp cams polymer gear with my non sleaved billet roller cams.

roller cams require the poly gear if it is not sold as one of the cams with a sleaved on distributer gear.
Your smarter buy the sleaved cam because these polymer gears are about $100 bucks and so brittle that if the teeth get hit they break off. I have 5000 some miles on mine and it still looks new.

It is a form of case hardening.
