440 cam selection question

Ported heads but springs for only .500 lift? The heads could handle that life totally unported. What was the point of the porting if not to take advantage of it? I'm baffled by that. But a decent cam for that combination with those springs limiting the heck out of it would be Comp's version of the Road Runner cam. It at least has Mopar specific lobes for the .903 lifter. I sure wouldn't run some generic cam with Chevy style lobes when you're already cutting your own throat with those valve springs.

I see you said "no Comp" but you can easily get Schneider or another cam grinder to grind one with Mopar lobes. Any of them can do it.
