if the cam and crank marks line up with the flywheel mark and the #1 piston is at TDC.......then im happy. So once the flywheel is on i dont need to reference the crank and cam marks anymore.
Good luck trying to make it start- - - -when the cam/crank timing marks are lined up, the #6 cylinder is in the firing position on the camshaft with both valves closed on the compression stroke.
