cam was installed at 108 . I also was wondering why the max power was before 6000. I know the headers used where smaller. I have a light car and advancing the cam I understand would move the torque and hp down the rpm range. This was a refresh with a bigger cam. I'm happy with the outcome. moved the timing ,around, retarding -4 . we added 100 rpm to peak hp and picked up 11 hp.Going to see if the aerospace vac pump needs rebuild. I would like to see more inch's of vac. hey maybe its the Dyno !
