Cams choice, Low CR vs VE%

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.

I agree with you that's my feeling on the subject but there a camp of guys that always argue the opposite and are knowledgeable guys, so trying to see if there is a theoretical reason to why this is the case, We known DCR is important and it's easy to calculate, increase VE% is speculative, hard to measure without a dyno so harder argue it's merits plus don't how a cam is gonna work with a certain combo bit of a guesstimate.
