Ford Timing Chain Sprocket Alignment Diagram - Cam & Crank Timing Marks

This document is a line-art illustration of a timing chain and sprocket assembly, showing the large camshaft sprocket at the top and the smaller crankshaft sprocket at the bottom, connected by a timing chain. A dashed vertical centerline passes through both sprocket centers, and a callout labeled 'TIMING MARKS' points to two dots — one on the camshaft sprocket and one on the crankshaft sprocket — positioned adjacent to each other along the centerline between the two sprockets (cam mark at the bottom of the cam sprocket, crank mark at the top of the crank sprocket). A red text annotation added by the uploader asks: 'This indicates TDC on the compression stroke...Correct?' The diagram itself contains no year, make, model, engine, torque, or part-number information; it purely illustrates the correct alignment of the camshaft and crankshaft sprocket timing marks when installing or checking a timing chain. It was uploaded to a 1978 Ford Bronco gallery alongside a Ford 351C/351M related document, suggesting it pertains to Ford V8 timing set alignment, though the document itself does not state applicability.
