Quote: I'm going to carefully step around the above and state exactly what I know on this subject: 1. There are no BBM / 426 Hemi billet cam cores w/ cast-iron gears pressed on available from any core source.
2. Although there have been cast cores used for performance roller cam applications for other brands, they have been given the by many engine builders because they don't hold up as well w/ the higher spring pressures that go along w/ those applications. You can do a search on cast roller cams on SpeedTalk.com to see some examples of this.
3. The only choice I have seen offered for hydraulic or solid rollers w/ a BBM or 426 Hemi is a billet steel cam that requires using the bronze distributor drive gear. I'm not thrilled about that either, but it is what it is at this time.
Although I have been told(not verified!) that Ruben cams(grinds for others) has other core options. Again,I have no evidence to back this up.
