Trick Flow small block heads

Impressive. Average CFM under the curve is 196cfm. While the higher lift number is better my edelbrocks only have a 276cfm peak but average 192cfm.

I myself am completely un concerned of the average flow area under the curve. Meaningless to me. I look at individual flow data at there lift points. Then I can compare. The area under curve is charted and drawn to give a visual of what’s going on. For me, seeing this is of the most important things I can do for myself while looking at head flow.

FWIW, this head kills my W5’s low lifts.
But I am moving a larger column of air through a larger port window with more cross section.
