made two pulls at 108 ,moved the cam -4 just to see what would happen we picked up from 763 to 772. when I get the car to the track i certainly will consider cam position during test tune session! love that Jesel belt! . performance will be the judge!! it may have been a little lean I ran the carb just the way it was.put away. I have the smallest .030 air bleed and 96 jet! thats exactly what the carb ran last season! that also will get changed to a 98.
