Hydraulic Rollers past 7000rpms

[ultraflo]

Does anyone know where I can get some hyd. rollers that will handle 7000+

I remember reading about some in Race Pages...

Comp Cams has had a "Pro Magnum" p/n 877-16
for a few years now but keeps pushing back the release.
These critters a supposed to be reliable in the 6500-7000 range.

I have heard horror stories about stock lifters past 6500.
When I had my car dyno'd Anderson would not rev it past 6500.
I have shifted at 7000 on the Autometer a few times on the street and when I made the only three passes that have been made on this new combo because it pulled all the way up to that point. I haven't puked a lifter yet and most certainly do not want to.

So what's up? Any info?
