Nismospek Posted October 9, 2018 Share Posted October 9, 2018 It appears that the Wako 75S has been discontinued and has been replaced with two cams, the 75R and 79 Special. I was able to find a little bit of info here on the 75R which seems to be a little less aggressive than the 75S. Still waiting to hear back on the specs for the 79 Special. I was able to find some info on the 75R from this website http://www.geocities.jp/kuni_s30z/lgata9.html. Wako 75S Cam Lift 9.7 mm Valve lift 14.4 mm ~ 14.6 mm Central Angle: IN 101 degrees / OUT 103 degrees Wako 75R Angle 75 degrees life 9.2 mm Valve lift 13.5 mm (lever ratio: 1.47 calculated) Center Angle (not publicized) Quote Link to comment Share on other sites More sharing options...
