What would it take to make 1.44 lbs-ft per cid ?
185-186 cc works out to be about 290-292 fps for a 277 cfm head and chart says should make very good hp and torque.
I've never said this chart is accurate or should be followed, but the little velocity information out there I'm using at a basis as I gathered info and seeing if this chart has any merit. J.Rob's heads where barely slightly smaller than the chart recommends and he did said that bigger was desirable when done right which would of be in recommended size. Now again not saying this chart is right but I'll put this one in the win category for the chart.
That chart is talking average. Earlie A did a whole thing on it, 350 fps average is the max velocity at 28" there no more energy to pull more.
