Timing of the Ford Early V8 Distributor

[Tienes que estar registrado y conectado para ver esa imagen]

These early V8 distributors (used 1942 to 48) were mounted to the front of the flathead engines. They were generally set for timing in a special fixture, but can be set in this way too.

Adjust the breaker gap to .014 to .016 inch. Make this adjustment by bringing a lobe of the cam under the rubbing block of the breaker arm, then loosen the gap adjusting screws and rotate the adjusting screw. The point sets do not open simultaneously; they must be set separately. Check with a feeler gauge.

Then put a rule against the tang on the wide side of the distributor shaft (note that the tang is offset) and rotate the shaft until the rule is set to the position shown. Be sure to measure from the mounting hole closest to the vacuum brake.

With the distributor shaft in the position shown, the left hand breaker points should just be starting to open. Note: the timing is controlled by these points only. If the points are not just starting to open, move the adjustment on the right side of the distributor down to advance the timing or up to retard it.

If the correct timing is not obtained on the first try, turn the distributor shaft back at least 1/4 turn to eliminate backlash and repeat the check.

Any difference in timing, that might be necessary due to grade of fuel being used, can be established by adjusting the vacuum brake. This adjustment does not change the basic timing of the distributor. A change in the spacing of the breaker points will change timing. However, the timing will generally be reestablished when the points are correctly spaced.

To adjust the vacuum brake, back off the screw until the engine pings on a road test under load. Then turn the adjusting screw in just enough to eliminate the ping. Tighten the adjusting screw lock nut.

Ford Cylinder Head Torque Specifications

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.

1932 - 1948

85 Horsepower V8 with Cast Iron Heads............................... 50-60 ft lbs

85 Horsepower V8 with Aluminum Heads.............................. 35-40 ft lbs

60 Horsepower V8 with Cast Iron Heads..................................... 50 ft lbs

60 Horsepower V8 with Aluminum Heads.................................... 30 ft lbs

Note: The specs for the 85hp would be the same for '39 to '48 models of 90, 95, and
100hp (239 cu. in. V8's) whether Ford or Mercury.

1949 - 1953

100-110 Horsepower V8 with Cast Iron Heads............................ 65-70 ft lbs
