So I proved you wrong with I’m assuming the video you posted, Because there’s only one video from GPI doing a test like that and it shows/Ryan even says the numbers from each intake manifold. 455 untouched lt2, 458 untouched msd, that looks like a gain to me and knowing that each dyno reads different that means the gain could be more on another dyno. Now port both, and that msd is going to show a decent gain. Now you want to call me stupid when you have a 416 that doesn’t make 600rw, when a 416 with 14:1 should clear 600 all day as long as long as the cam is spec’d for the 416. That 416 makes that NFC look/act small, it “eats” up the duration and causes the cam to act even more mild than it already is.
