Has anyone use Chris Straub roller cam in there 496 stroker olds engine looking see what spec and horsepower rated thank

 

Straub doesn't advertise Olds grinds. I would guess they don't have their own grinders and instead have an agreement with a typical cam company. They might have their own combination of catalog lobes, or maybe some tweaks to some standard lobes.
In any case, I doubt their cams are especially magical or different than any other.
