Update and a damn good read!. February 2014 issue of dsport magazine. They themselves just did a unbiased evo cam showcase. Part 1 only showed a few cams that were tested and all the other cams will be shown in part 2! They show the real duration (
cam pro analyzer) vs advertised and also dyno'd them. I linked pics of the article. Which shows the kelford 264, 272, and 280 real cam data!!!!!! Down to the volumetric efficiency of the cams.....throughout the rpm range!!!
