the timing marks i know. the positioning of them is the question. the chiltons says that for only the 90-91year modles the marks are to be set with the cam mark at the 12 oclock position and the crank mark at the 230 or so position (near three oclock per book) so that there is 15 pins between the marks. is this something new in engine rebuilding or do it old school and set the marks as in your picture?
