Stroker specific cams?

Yeah, I'm not getting the proprietary lifter thing either.

I won't lie when I say I'm not sure what's out there for a HR lifter any more, as I won't use them. Ever. I'm not sure Mike Jones has an IR roller lobe for a HR lifter, because how in the world would the hydraulics handle that?

BTW, the ONLY IR lobe roller cam I'd buy is from Jones. PERIOD. He is the ONLY grinder I know who uses a 5 inch wheel (or some damn small size I know it ain't very big and IIRC that's what he uses) and you can't get a real IR lobe with a big grinding wheel.

There may be an issue with using a .750 wheel with an IR lobe but what little testing I did on IR lobe stuff was in 87-88ish with Crane lobes and that thing was a spring eating nightmare and RPM made it worse. So I'm not sure for the RPM range the OP is taking about would need an .810 wheel. I mean, I never like to use a small GM sized wheel (all the bigger you can get in a .842 lifter bore so they've been seeking GM junk to Chrysler guys for decades and not giving a crap) but with a HR lobe you may not need the bigger wheel.

Like I said, I'll never use a HR on anything again. I would use a HR lobe with solid lifters on it, but no HR lifters for me. Even at the OP's RPM range.
