Does anyone like Injector Dynamics match small injectors at multiple points? If I were to upgrade an older engine from single point, I would probably be flow balancing the rest of the engine.

Actually I shudder to think, on a 302HO inlet manifold flow @28" can vary by 25% runner to runner. Assuming that makes a 10% dynamic airflow difference and the injectors at low pulse-widths can vary by another 10%... that makes for a potential air-fuel ratio mismatch of 22% or so. Which with a target of 14.7:1 is a range of 17.9-11.4:1
