Cams choice, Low CR vs VE%

273 said
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.

because flow trumps compression. Ideally, flow with compression is optimal. But when bumping compression isn't in the budget, they chose flow over compression. Yes, they will bleed off a little compression to gain flow. And guess what? It works just about every time it's applied.
