| Please note that the following specifications and related information are derived from a variety of sources (including Ford shop manuals and industry shop manuals) which may show slightly different details or specs. In general, you will find that the information given is pretty common and straight forward. Also note that these relate to stock Ford and Mercury engines. Any aftermarket cylinder heads (such as Offenhauser, Edlebrock, and others) will call for different torque specs, even though the tightening sequence may be the same. Aluminum heads call for lower torque specs and it is recommended that the mechanic re-check the torque after the engine has run up to temp and then cooled (in other words....after it has cooled from running). Some owners will re-check all flathead torque settings again after the first month of operation. It is also suggested with aftermarket heads that you "clay" the heads (place modeling clay in the chambers where the valves rise) to check valve clearance before the actual torquing of the studs/bolts. A clearance of .040 is a minimal amount. With the heads mounted (without gaskets) and hand tightened, rotate the engine so that all valves have a chance to open and close. At any points where the valve has moved the clay away from the combustion chamber metal, it may require some grinding to provide clearance. The gasket thickness must be taken into account. In general, all torque sequences shown below reflect a gradual tightening from the center of the head outward, alternating from side to side and top to bottom. Some diagrams mirror the other diagrams, but essentially perform the same gradual tightening operation. All manuals suggest that the mechanic coat the threads with a thread sealer before installation. |

Flathead Ford Parts Drawings
You'll find many black and white exploded parts drawings and diagrams here. The part number identification (where included) is limited to the basic Ford part number. Refer to industry parts manuals for specific part number identification to a model or year. The picture files feature the engine itself and various drive train components, but there are other general interest pictures too. There are plenty of parts books available on the market if you are interested in obtaining more specific information. The picture files linked to this page are for your reference and enjoyment, and are not for commercial or resale use. There are many parts breakdowns printed over the years and we are not able to include them all. Additional picture files will be added as time permits. Check back with this site for new pictures in the future!Home Parts Drawings Web Links Tune-Up & Service Serial Numbers Engine ID Trans ID Model Identification Terms of Sale Contact Us Our Online Store Our Catalog

ENGINE SERIAL NUMBERS
The engine number was also the serial number of the car. Engines were numbered when they were completed, and for the most part went into a chassis within a day or so. However, some engines were assembled and numbered at branch assembly plants. Highland Park would ship a block of engine-number records to an assembly plant and these engines might be made weeks or months...07-31-2018, 10:57 AM -
My roadster has a 3.78 rear end, 6.0 head and a F150 4 speed trans.
I have taken the RPMS with my Westech tach, a dwell meter and a digital timing light, and i am not sure about accuracy.
