Some people have been doing it for years. There are some hyd listed grinds that are the EXACT same lobe as the solids but with a different part number. Of course there also have been hyd flat tappet lifters run on some solid lobe profiles too.. BUT for specific reasons. .... Crazy track rules back in the old days!

No track times today. The weather got us. We hope to race tomorrow(Sunday 3-15-09). If we race tomorrow, I will run both Top Et & N/E to get more runs on the new set up.

+1 on this info!! Comp sure is good with advertising, meanwhile other cam companies have been doing the exact same thing for around 15 years.
