Cams choice, Low CR vs VE%

Why I started this thread is about adding cams to stock low power cr engines, 273/318/340/360/383/400/440, and almost anytime the subject comes up DCR always enters the conversation, not saying CR and DCR isn't important obviously it is but people dealing with stock long blocks really are stuck with what they have.
So my question is adding a cam even if it sacrifices some DCR for added air flow, guess which means more VE%, not talking big cam high rpm but in the street rpm idle - 5000.

Adding a large cam to an engine with low compression will have the same effect as adding one to any engine. It will increase the peak power and torque, but move it higher in the RPM band. Just like any other engine. Probably "not as much" as one with an optimal compression ratio for the given camshaft, but it will increase nonetheless.
