Dyno #'s with Trickflow Heads

Where did those power curves come from because they aren't representative of the OP's numbers. If that's desktop dyno, I bet the numbers for the EQ heads are the manufactures flow numbers.

IIRC, the flow numbers on Brians stuff was around 270 at .500

Valve lift Intake Exhaust w/1 3/4 pipe
.100 69 58
.200 141 119
.300 197 161
.400 241 184
.500 267 193
.550 271 195

With the cam in question the 400 flow rate is going to about where the window is likely going to be effective.
