Comments: The truck pushes about 38 square feet of air and has 67% weight over front axle. Cam was installed straight up to kill the bottom end a little. I advanced the cam later to 104.5 and didn't see a change in performance. Also switched to a 850 holley and picked up 2mph. I tried a MP 590 mechanical degreed at 100, no change in performance over the 509. Tried a BG 1140 stageIII reaction time 3 circuit dominator, 60fts. stayed the same but ran 2 tenths slower. Was lean at WOT, not enough motor for it.
