Not entirely true.... 7.3 diesels were not mandated under federal regulation to be enviromentally clean (with no EGR), it was in 2000 that Ford was served notice by the EPA backed by the US Congress to clean up there diesels, hence the 6.0 with EGR's in 2003. Only reason why Ford did it because a fleet of 7.3 Diesels consisting of more than 100 trucks would emit more than 20 metric tons of carbon per year. EPA presented this to Congress and they hit ford hard (largest truck seller) changing to the navistar 6.0. Thats why it is important to purchase a late model 04 motor in 05 trucks. Most kinks were worked out.

 

Both you guys are wrong... Ford doesn't make either of those engines. Navistar/International does.....

 

I actually knew that also, but when anyone says navistar, they will fight till they are blue saying it is a ford motor.

 

Not really.... I never said Ford manufactured either engine. When I used the word "produced" I meant Ford hasn't brought forth anything as far as a diesel for their trucks that is worth a damn sense the international 7.3. Ford just started in 2011 manufacturing the 6.7L powerstrokes inhouse for the Super Duty trucks. Hopefully it will turn out to be a good engine.

 

i got my 01 thinking about selling but not sure it has the 7.3 in it but has over 100k right now its been sitting for 2 months with my f250 bought 4 cyl cars to drive around and parked the trucks i bought it at gibson truck world in sanford
