Cathedral vs ls3 test on a 408
I'm with you. It's kind of a pointless test unless the cams are also switched. That being said, I bet the LS3 heads and this cam still make more power than the 317s with an appropriate cam.
Yeah surely, the LS3 is larger and better suited for the airflow demands of a 408ci shortblock. The smaller intake port in the 317's needs more intake duration IMO, so I suspect that helped widen the gap between the two.

Ham makes threads like this to make himself feel bettr. Stoopid compare. A head that cant flow near 300cfm to a big square port on a 408ci stroker??
Put both those heads on a 4.8 or 5.3 w/ a cam speccd for the cath heads. Hmmm, motor more suited to smaller heads along with cam. 180 from this test.
Ham knows in his heart which head is always better.
