I thought this might be worth sharing from the 383 mopar intake test done by HRM years back. These were on a 383 with 10:1, 263/267 @ .050 with .646/.648 lift, and CNC'd Edelbrock RPM heads.
Here's their flow chart:
Lift I E
Lift I E
0.100 74 64
0. 200 148 116
0. 300 211 155
0.400 255 188
0.500 293 208
0.600 308 225
0.700 317 236
And here is TFS's flow chart on the PP240 heads
.100 I 72 E 58
