  1. Can I put a Cummins engine in my truck that had a gas engine in it previously?

    Yes. It’s a bit more work and you will have to buy a few more parts like an intercooler, exhaust, & possibly a diesel radiator.  For automatic transmissions, an OEM diesel torque converter plus you'll also have to get rid of your in-tank fuel pumps.

  2. Can I use my Ford transmission?

    Yes. Diesel Conversion Specialists® currently makes 15 different Adapter Plates that allow you to bolt a Ford transmission up to a Cummins engine.  Ford transmissions work better in the conversion because they are OEM equipment and well known to be among the best transmissions available.  Even if you don't mind a bit of fabricating to use a lesser transmission be advised; some of the older, 1997 and later, trucks use a cable to drive the speedometer creating another potentially costly hurdle to overcome if you want your factory instrument cluster to work.

  3. Can I use the stock Ford gauges in my dash?

    Yes. We sell a sensor adapter kit that includes adapters to help you install the stock oil pressure and temperature sensors into the Cummins engine. The stock tachometer will work with our Tach Kit, and we include the instructions to help you get the wires all reconnected to your sensors without modifying the instrument cluster or removing the dash panel. In your 6.0L and 6.4L truck you can also expect your boost gauge to work.
