Thanks Tim.
I measured off the top of the follower, so it should be a 1:1 measurement. Is the max lift rotation angle that is recommended for inlet and exhaust, independent of cam type? I was assuming that the lobe profile might vary from cam to cam model, but that they would be centered at the same location on each different type. Is that a fair assumption? Otherwise - I don't feel like I can check or set anything on these cams unless I can positively identify which ones they are. Can anyone advise?
Thanks,
Justin.
typo 64mm = 6.40mm.... 109mop is for the std cam. Var and others have higher mop for inlet and lower for ex. By c3deg. These cams are generally symetrical. Bear in mind clearances need to be deducted from lobe measurements.
