767 Driver...the hydraulic rollers tend to have iron or hardened steel gears pressed on the cam, even for FE applications. The mfgs are less inclined to do this on solid roller FE cams...just a smaller market and because they tend to be utilized more in racing environments where regular engine teardowns minimize the need for anything more durable than a bronze gear.

That's all generally speaking, of course...and composite distributor gears which are more durable and yet won't eat the billet of a solid roller cam may be the ultimate answer, but five years later, the adjectives "new" and "experimental" always seem to be in play during discussions of them.

Remember...this thick-headed Armenian ignored three FE gurus and tried the solid roller anyway. Trial and error be an asspensive method of learning stuff.
