Don't any of the cam manufacturers make billet steel cams with Iron Gears (distributor drive gear) for your Ford engines?
I've run roller cams in Chevys for years (>13 years on the same roller cam and dist gear in my BBC Vette) with standard distributor gears (that don't wear out like bronze). The key is to order the version of the steel cam that has an Iron distributor drive gear. As I recall the Crane cams simply need an "IG" designation at the end of the standard steel cam part number.
This returns the cam gear/dist gear configuration to the same long-life, high reliability combination as used in factory engines for forty or so years...
Just thought you guys might want to check with your cam vendors. Simple solution. No "special" dist gears required. No issues with extreme wear...
Now the oiling issue is something us Chevy guys know how to solve in our engines easily also. Usually a small (.030 or so) groove in the lower ring of the dist housing where it passes thru the aft cam oiling galley. This basically squirts
oil onto the cam gear. I am not certain this is necessary in Chevys, but I've always done it.
