CUSTOMER PURCHASE OF 427 CID HIGH PERFORMANCE ENGINE FOR FORD OR FAIRLANE
PASSENGER CARS
High Performance Engine Operating Characteristics
In a continuing effort to satisfy every demand of its customers, Ford Division
of Ford Motor Company is now producing special high performance cars and
components designed exclusively for use in supervised competitive events.
These special vehicles and components are not intended for highway or general
passenger car use.
Any customer wishing to purchase one of these special high performance
Fords or Fairlanes must be made aware of the restricted use as stated above
and advised of the following unusual operating characteristics:
A high idle speed of 800 RPM or above is required to insure adequate lubrication
and to minimize engine roughness.
The long duration camshaft causes a rough high-speed idle and may result
in poor low speed response.
Oil consumption will be higher than normal because of increased lubrication
to the valve train and cylinder wall.
Gas mileage is considerably less than a conventional car due to carburetor
calibration and the use of high numerical axle ratio required for good
acceleration.
Engine noise will be objectionable due to increased piston clearance and
mechanical valve tappet clearance.
The ignition system must be kept in top condition. Spark plugs and ignition
points should be inspected, adjusted and replaced more frequently than
would be required on a standard engine.
Band adjustments must be made more frequently on cars equipped with automatic
transmissions.
Operating expenses will be high since premium fuel is required and frequent
oil and filter changes are mandatory.
A vehicle equipped with the high performance engine is designed for competition
and is expected to be used for such purposes. The standard vehicle warranty
coverage will not apply, and the special warranty provisions applying to
vehicles equipped with high performance engines are to be explained by
the selling dealer.
I have reviewed the foregoing information with full understanding of the
operating characteristics and the special warranty provisions of a Ford
or Fairlane vehicle equipped with a 427 CID high performance engine.

Ford wanted to make sure that its customers who purchased vehicles with
the 427 high performance engine knew what they were in for. Oil and fuel
expenses were much higher with these engines, and they required more frequent
service than Ford's tamer engines.
Additionally, they didn't run, sound, or operate the same as the V-8's
people were familiar with.
Customers were required to sign a confirmation (text shown at left) that they understood the nature of the engine, and its higher maintenance
and operating costs. Further, they acknowledged that Ford's standard vehicle
warranty did not apply to this engine, and that the engine and vehicle
it was installed in were not intended for highway or passenger car use.
