I have been burning the midnight oil trying to figure out a cam for my 408 build. I stumbled onto the linked article , which made a lot of sense since my build is somewhat close to this in many ways. The cam is for a Ford small block, but it would seems like they could put it on a Mopar core. I might settle for a little less duration, but the theory seem sound.
