Thanks for the leads! I have no intention on using the lifters I posted. Just thought Id share what I was dealing with.
I didn’t think anyone would have roller cam cores for the Dodge low deck. From what I have been able to gather, the 241/270 low deck blocks have different lifter bank angles compared to the 315/ 325 inch tall decks. That in itself scares me. Looking for a cam grinder that knows that there is a difference may be difficult. I looked into making 3 billet UGL cores. They don’t need the gear, so they would be simple to make. Just not sure about the treatment/ metallurgy that goes into a core.
Again, thanks everyone for your help.
