Solid Roller camshaft selection those of you running a 408 race application - lobe seperation

Guys I am now working with Racer Brown for the recommendation. He went as far as saying he would grind two lobes on a scrap cam and send it to me to check clearance prior to grinding my cam. I’ll let everyone know the specs once I run the car. He has years of dealing with mopar combinations and dyno results. Will it be the best cam? Not sure, but will probably be one of the better educated guesses. Ty all tho I like reading all the feedback and opinions.
