I'm putting a distributor in my 79 Ford 351 modified 400 351 crank but 400 big block .. i know it is off of time and the timing chain is still good .. but how do i time the 1st cylinder with the distributor . how do i get it firing in order ?
The firing order of the 351 Cleveland, 351 Windsor, and 400 are all the same at 1-3-7-2-6-5-4-8 Rotor turns counterclockwise. Get the #1 piston, which is the piston on the front of the engine passenger side, at top dead center, (TDC) on the compression stroke. Turn the rotor on the distributor to the #1 spark plug on the distributor cap and insert the distributor into the engine. Time the engine with a timing light.
of course.
need to know the spark plug gap for a 1979 Mercury Grand Marquis with 351 modified.
1-3-7-2-6-5-4-8
if it is the stock engine then it is not a 351m because ford had stopped making the engine before 79
Firing order is : 1 3 7 2 6 5 4 8
point gap 1978m ford
not very much
It has 325hp and 375ft. torque
the dist. is just stuck try turning its base with a pair of channel locks there is also an o ring on the dist. shaft that also has the dist. stuck
Take the distributor cap off an crank the engine or turn the engine by hand clockwise and note the direction of the distributor rotor.
For a 351m engine the oil sending unit is located on the top of the engine between the carburetor and the firewall.
1-5-4-2-6-3-7-8 Distributor rotates counterclockwise.
