340 Engine Shake

One thing I haven't been able to get over with a roller is the distributor drive gear.
For a street car, a bronze gear seems dumb.
The melonited gears seem like unobtanium?
Not sure what other choices are out there, but there's lots of confusion.
Stock magnums ran hydraulic rollers and didn't have bronze distributor gears.. Curious how all that shakes out, because I'd love to run a decently hot solid roller, but I only drive mine on the street..
Cams ground from a billet cam core require a billet "bronze" distributor drive gear.
Cams ground from a cast cam core use a cast drive gear.
It's a material hardness compatibility issue
