You have a big job ahead of you. Make sure the engine you want will bolt up to the transmission. Is the rear end stout enough to handle the torque of the diesel? Will you need alterations to the drive shaft. Now check the suspension requirements, it will probably requiring beefing up. Removing the gas tank and cleaning it out will be a requirement. What about the fuel pump, and fuel lines. Now the good part. All the little gizmos and computer sensors, relays, etc which is not going to be present on your gasoline engine.

I have a 3/4 ton rearend off a ford superduty for it and I plan on putting a alison trany in it. For the electronics I have been told that the 5.9 12v dosent have a bunch of electronics. Iv also been told that they sell kits to help this change over.


True, the diesel is much simpler, electronic wise" than a gasoline engine. You'll still have to match parts to each other then match them to the model of your vehicle. My biggest concern will be the front suspension and the braking system, especially if you intend to use the vehicle for the purpose it is being built.

Carl: I'm going from memory now, but the block and heads are iron and I believe the engine assembly weighs over a thousand pounds for the diesel. I doubt the 4.6 V8 comes in at 500 pounds or maybe a little more. Hence the concern about the front suspension and brakes. Your front will sustain most of the work when trying to stop that monster.

Will a 3/4 ton front be enoff or will I need to go with 1 ton .I have already put 3/4 ton suspension. I havent done anything with the breaks, I have put heaver balljoints and control arms and tie rods on it. I started this to make this capable of pulling a larg 5th wheel. So I changed all my suspension to 3/4 ton.


Carl: My nephew built a couple of the vehicles you are interested in. He has never used the F-150 for the build. He has used the F 250 or F 350. Without going into great depth he stated an upgrade to the tranny is required (rebuild) and an adapter plate hookup to bring the two together is necessary. Mounts and radiator will also be necessary, along with an intercooler. He suggested you visit WWW.fordcummins.com for info. There is a phone number you can call. Tell them what type of truck you currently have and they can send you a kit to convert the truck. Although he is not sure about the base F 150 model.
