By better numbers are you meaning peak horsepower, or larger area under the curve? I think that the low lift, low duration cams give a wider operating range, where the higher cams are only efficient at a smaller specific rpm. Orrrrr I could have this logic completely backwards. Itd be pretty cool if it were possible to see the pressure and flow differences of an individual runner throughout the RPM range.
Originally posted by MoparDSMYou're absolutely right, and my curiosity is stemming from why people are seeing better numbers going with the low duration, low lift 264 on small builds. I am hoping to take my setup, with the unported 2g head and matched unported intake manifold with the 264/272 get some numbers, then change nothing and slap another 272 in there and see what happens.
