Not Ranked

Oh I see, the first reference is from the second MM&FF Ultimate Cylinder Head Guide test using a 331. In this test, the GT40X showed average 315HP and 386TQ versus 343HP and 417TQ for the AFR 185 versus 339HP and 411TQ for the Z head. In addition to more cubic inches, this engine also sports a more aggressive cam - XE274HR versus the XE264HR for the 306 engine used in the first Ultimate guide test. Apples and Oranges.
