69-79 Ford - Overview
What does it take to put a Cummins in my 1969-1979 4x4 Ford?
Here is some information that will better prepare you for this conversion. Necessary parts are highlighted.
For cooling you can use a 460 radiator or a Ford diesel radiator. When heavy work or performance is involved it is best to consider a larger radiator; remember, the more cooling the better. For everyday driving the 460 rad. is fine.
When using an intercooled 12V Cummins (91 or newer) you will want to use a 99+ Ford Intercooler or a 91-93 Dodge Intercooler. With either of these intercoolers you can use the 460 radiator.
If you choose to use the 460 radiator with the 99+ Ford Intercooler, just note that one neck on the intercooler may require a slight modification in order to clear the radiator (cut and weld).
Gauges
We provide you with a bushing kit that will help you install your Ford oil pressure sensor and your Ford temperature sensor units into the Cummins engine so that you can simply plug them back in to your existing Ford engine harness.
Revision To Be Made:
To the Truck:
- In some cases the fire wall will need to be adjusted (with a hammer). A body lift is not necessary, but can sometimes give more room.
- In most cases there is a bit of drive line length adjustment to be made.
- The transmission cross member usually needs to slide back a bit. Some times it needs to be revised or restructured a bit as well depending on which transmission is used.
- If your gear ratios are 4.10 or lower, you may consider a higher set (such as 3.73's or even 3.55's [or whatever similar ratio is available for your particular truck]).
- You will need to trim the back side of the grill a bit to properly fit the intercooler.
- For trucks that have A/C we use the Dodge A/C pump. In these older trucks there is a bit of fab work to properly fit this pump. (It is on the bottom passenger side of the engine.)
To the Ford Transmission:
Our custom Adapter Plates use the your existing Dodge style starter that is already on your Cummins. The starter ends up in almost the same place that the Ford starter was, only it has to be a little bit higher. This requires you to trim your bell housing where the starter will otherwise hit (as illustrated in manual). You will also need to trim the Cummins engine block a little bit in one place to allow the starter to go into the adapter plate straight. (also illustrated in manual).
Wiring:
12V: These are all easy to wire as they are manually operated engines (explained in installation manual)
24V: These do have a computer but are not too bad to wire as we sell a simple instruction sheet that will help you get the job done.
