That makes alot of sence now lol I gotta check on that then cause I planned on using my original intermediate shaft I may have to buy a new one. I'm using a lunati voodoo cam hydraulic flat tappet.
It would be unlikely any hydraulic flat tappet camshaft would be anything other than cast iron, but check with Lunati on the one you are looking.
If it's cast, stock intermediate shaft gear material is compatible.
