I've been down this road that you're on about a year ago. No one, repeat, NO ONE, makes a hydraulic roller cam for an inline six cylinder motor.
I guess you must have missed the discussion thread here several years back where I made a half a dozen billet round lobe roller cam blanks to get ground as hydraulic rollers. If the demand warrants it again i'll do it over. The 4 cylinders as well.
You're right, I did miss that. I was off of the Bulletin Boards for the last few years, so there were a lot of things that went by that I didn't see. I've thought for some time that if you could grind the taper off of flat tappet cam lobes and reharden the lobe surface, you could use hydraulic rollers. Or as you did, grind a billet camshaft for use with hydraulic rollers. I'm glad to hear that I'm not the only one who has some interest in that area.
