You may not need it, but dual pattern cams can have a serious power advantage, and from what little I know, are very effective. I put together a 408 with Magnum EQ heads, dual plane intake, 10/1 compression. Cam is a Comp Muthr Thumpr with 235/249/ 107 LSA duration. It made 500 hp from 5200 to 6100 rpm,519 TQ at 4100. You can and probably should have a custom grind made just for you.
and if you are looking for off the shelf, Hughes Engines has a wide variety to choose from. They are the small block Chrysler guru's IMO.
