360 Street/Strip Cam?

I'm almost wondering if it would be best to buy a block, get it machined, and slowly start to build it up. I guess adding a cam to a stock engine might do more harm than good. Would there be an option for a mild cam that's better than stock then?
Just grab this now:

ATK High Performance Engines SP61 ATK High Performance Chrysler 408 A Stroker Short Blocks | Summit Racing

before it’s gone and you have to wait till who knows how long for a similar option (I’d have said to get a Blueprint stroker short block but they aren’t offering those atm) and build times are really unknown with parts availability issues for all.
