I didn't hear Joel Beltramo, Chief Engineer of the upcoming Ford 7.3L gas engine say or even suggest what ShinerBlock heard above.
At 2:41 in the video, Mr Beltramo said that there WILL be "subtle changes for the chassis cert engines"... but that the "dyno cert engines are almost identical", and said this while he was talking about the value to fleets from an in house service training perspective of having an identical gas engine in all trucks in the fleet.
To understand this better, some may or may not understand the difference between chassis cert and dyno cert, and might mistakenly associate "chassis cert" as applying to "chassis cabs", when they are unrelated.
Chassis cert applies to F-250/350/450 pickups, because for EPA emissions certification purposes, these vehicles are final stage completed vehicles with a known body (pickup bed) installed, and therefore the entire chassis is certified.
Beltramo specifically said that "chassis cert" engines will have "subtle changes".
Dyno cert applies to the F-350/450/550/650/750 chassis cabs, that Ford sells as incomplete vehicles that have no bed body and have not entered into their final stage of manufacture. Therefore, for EPA emissions certification purposes, the emissions for these engines are dyno certified only, because the ultimate characteristics of the final vehicle are unknown and not determinable by Ford.
Beltramo said that "all dyno certs are almost identical".
THIS is the news... that there will be almost identical characteristics among the dyno cert engines throughout the chassis cab line up. He did NOT say that the chassis cabs (dyno cert) will be identical to the pickups (chassis cert). As specifically stated, the pickups (chassis cert) engines will have "subtle changes" from the chassis cab (dyno cert) engines.
In the last 7.3L (diesel) from 20 years ago, there was a big differences in the dyno certs for F-450/550 chassis cabs (235 hp) versus the dyno cert for the F-650/750 chassis cab (190 hp). In the outgoing 6.8L V10 gas engine that the upcoming 7.3L gas engine will replace, there are again fairly substantial differences between the F-450/550 dyno cert (288 hp) versus the F-650 dyno cert (320 hp).
If one listens carefully to what Joel Beltramo actually said, the difference will be more clear.
