Ford V10 to 12-Valve Cummins Conversion

We had the bright idea putting a 2nd generation 12-valve Cummins in our 2000 F350 to replace the depleted V10. So with a little help (a lot) from DieselConversion.com, we managed to pull it off without too many hiccups.

With a little over 100,000 miles on the truck, we thought it would be a great application, taking our weakling of a truck to a diesel monster.

The whole process will be posted.

The new Cummins

We did some serious looking to find the right motor, right mileage, right year, etc….

With a little steam cleaning and paint…

At this point, it would be good to mention that the parts that were used to make this conversion possible were provided by DieselConversion.com. In the above picture, the obvious would be the un-rusty header that clocks the turbo downward for clearance in the Ford.

Before we made it look all pretty, we had to do some enhancements of which included installing a piece of metal to keep the “killer pin” from working its way out and reeking havoc.

The picture below depicts the small highly customized piece of steel that holds the pin.

Transfer case had to come out reason being that our transmission needed some work.

With no tranny jack, things got interesting real quick…

It was a little difficult clearing the oil pan over the cross member with the cab still on the truck.

Our particular truck spent its early life in the north with heavy snow fall, salt had taken its toll on the underside. So we cleaned it up and did some painting.

The old V10 that came out of the truck had an issues with the cam shaft being worn in the block. It would produce a knock on cold start which would go away as soon as it was warm. Power was also definitely lacking.
