I agree with everything that is said on this page. I do use alot a Crane Master Lobes because they seem to have the best selection of cores with pressed in cast dist. gears on there billet cores. Have seen many used in offsore racing and never any problems. I also had done many Cam Motion cams with the Melonized gear and have never had any problems. But have had been concerned about what happens when the coating wears off? I did have a steel core that was not hardened properly it looked just like Vintages picture after 700 miles. I really don't like the idea of Bronze being called a wear item, I don't like any type of material in my oil. We can also talk about Composite Gears..If the cam core gear is prepped very good, they will look brand new after many miles. if not they can make a mess of things real fast. The other problem with them(more of a Ford problem) is No press fit. I do not like the Cast Cores, Very Hit or Miss.. Also in the 1985 years. I built many LB9s L98s and 5.0 Fords. For Showroom Stock racing. First year for OEM rollers, I Believe they were steel not Cast, I remember them looking completely finished with a heat treated look. No casting flash. I sent a few to have them to be reground and was told that they were steel cores.
