Yea i believe ford had initially fielded the international 7.3 LP mechanical diesel in their first diesel civilian truck. Then they licensed HEUI from cat and produced the 6.0. Like most all firsts, it has it’s issues, but many have modified them and have made them quite reliable. Ford, like Toyota with its initial EFI teething problems with the 2.4 and 3.0 morphing into the very solid 2.7 and 3.4, Ford morphed the 6.0 into the 6.7 and fixed most of the issues. I don’t follow them too closely, but I was thinking that they re-imagined the 7.3 in a HEUI configuration. I havn’t played with fords since the 6.0
significantly wider than a inline 6, probably not as tall above the crank but the rounded doghouse edges will limit the height at width. Then there are other issues, such as interfacing a light duty diesel onto a medium duty transmission(have no idea what interface Ford designed). If it is HEUI you will need to figure out how to get TPS into the trans controller… the ford HEUI does not use a engine lift pump, but a frame mounted 60PSI electric pump, like many EFI vehicles. Issues with them and the pressure reg in the 6.0 is where we learned that HEUI injectors do not long survive low primary feed pressures. There were a couple vendors who offered low fuel press idiot light kits for the 6.0.
And as general mentioned, the air compressor will be fun…
