intake & carb for built 318

I am running 3.55's with a built 727 manual valve body shift and stock converter at the moment, was thinking of going for a 2500. But by all means if there is a cam you can reccomend that will fit the build perfectly I'm definitely not opposed to getting another one, it's just what came with the motor that hershberger put together, but I'm sure he had some worked heads before. So was hoping it'd work, if not, I'm all for switching up
