[QUOTE="twistedneck, post: 12778831, member: 130159"] quick compare of the stage 3 to stock coyote and the cobra jet cams.. those stage 3 cams are beasts. coyote stock - best info I could find please fix if you know the exact values. intake 12mm lift, 211 duration at 0.050" lift, 260 advertised exhaust 11mm lift, 211 duration at 0.050" lift, 263 advertised cobra jet - estimated based on what ford racing provides and stock coyote cams data. intake 13mm lift, 213 duration at 0.050" lift, 263 advertised exhaust 13mm lift, 232 duration at 0.050" lift, 290 advertised stage 3 comps.- these require 20 degree limiters for piston to valve. intake 12.5mm lift, 236 duration at 0.050" lift. 276 advertised. exhaust 11.5mm lift, 239 duration at 0.050" lift. 283 advertised. you can see that the comp stage 3 cams are oriented towards maximum rpm.. not sure if the reduced lift hurts anything with a 4 valve head. these are the NA cams not the blower cams. edit - here I found there is one more even bigger cam from comp. its called the RACE1. (stage 4?) 14.5mm intake lift, 240 duration at 0.050" lift. 13.0mm exhaust lift, 242 duration at 0.050" lift. I don't know why the skew the lift to the intake side except there may be a limit on the max lift of the coyote head architecture. [/QUOTE]
