Looking for stock 318 (72) cyl head flow data, with 1.78/1.50" valves
I am running the COMP cams CamQuest6 program for cam selection, and in an effort to gage accuracy, I was hoping to benchmark my current engine as is, with correct flow data.
The program does not include that cyl head above.
I then want to run several scenarios in addition, including a worked/ported 318 head with 1.88" valve and then again with a 340 cyl hd (X) with 2.02/1.60" valves.
I have the 340 heads ready to go. Makes sense to just use them, and adjust compression.
Funny thing was, that after running the 318 through with the 340 head and flow data, I saw hp barely change when I punched the bore 0.040" on several cam suggestions. Torque went up though.
Thanks.

Thank you , that is exactly what I was looking for, flow at different lift points.
They had both stock and ported 302 heads, and man did they make them flow great after porting. Better even than X heads.
