Distributors
All M-block (351M/400) distributors are mechanically
interchangeable with
all 351C engines and all 385-series (429/460) engines. However,
much
like carburetors, distributors are calibrated for a specific
vehicle and
engine application.
Distributor calibration includes:
-
Vacuum advance specification — total advance and threshold
vacuum
-
Mechanical (centrifugal) advance specification — total
advance and “curve”
(i.e., the rate at which advance comes in and the engine
speed at total
advance)
The following tables list calibration ID codes and Ford service
part
numbers for M-block (351M/400) truck engine distributors.
These tables are organized by model year and truck model, with a
complete
table for each model year from 1977 to 1982.
Some of these distributors are still available as brand new,
complete
assemblies from Ford. Prices range from under $100 to over $500
each.
Unless obsolete, you can use the Ford service part number to
order one
of these distributors from a Ford dealer parts department.
