More hot air and bullshit. Like the song says, "A little less talk, and A LOT more action". $38 Trillion in debt and rapidly growing. Window dressing and hot air ain't gonna do it.
If it's an inline six, and not a Cummins, it's likely one of Ford's Brazilian tractor engines they were pushing in the medium duties at the time. IIRC they had 6.6 and 7.8 liter versions.
On Edit:
Cummins would not have been an option at that time. The other choices would both be V-8s, 3208 CAT...
Nixon and Kissmyassinger definitely opened Pandora's box playing pattycake with the Chi-Coms. They never were, are not now, and never will be an "ally", as the globalist morons like to say. They would like nothing more than their boot on our throat.
