a good "air day" is 7500 da. a bad day is 9800da

I feel like i have enough head flow, but wonder if my intake is restricting me. Not enough cross sectional area............then i factor in the rpm and DA and wonder if it's a waste of time.

Victor hands down. Maybe a Strip Dominator if you can find one.

At your displacement the LD is choking the engine. It wasn’t designed for that many inches.
