Art,
i have used the composite gear for a few years now and am really happy with it,i also use a composite fuel pump pushrod with a holley 200gph mechanical pump,it is just starting to show slight wear but not bad at all.street/strip deal

It depends on what the cam is made of. Being a solid roller doesn't guarantee it's one certain material. Though it's said that a composite gear can be used with a cast iron, ductile iron, or billet steel core. I haven't used one on all 3 cores so I really can't say.

i have and still using composite dizzy gear on comp billet roller,2 x comp solid flat tappet cams,lots of street miles and track passes.i am using a MSD distributor with adjustable slip collar,need to make sure you have correct clearance and gear mesh or any material will wear very quickly.

hef af2 what does melonized n=mean, i have seen that name to go along with gm engines. is that a stock type of metal or some type of special alloy?. thanks art

Lunati has a gear called "Everwear". I ran one on a billet roller cam for a long time with zero issues. Should give you excellent life without the wear issues of a bronze gear.

Art,
The correct answer is to call the cam manufacturer and ask them. A lot of the cams now days are made with a pressed on gear and back bearing and can use a completely stock distributor gear. I would not take a chance on guessing. Call the manufacturer and ask them.

It's an option I've gone with on several Jones solid rollers. All good so far.

Yes with the cast gear option you can run any distributor gear. With the billet the gm MELONIZED or other everlast gears are a must and will hardly ware.
