I’m pretty sure the GM fix is heavier oil. From 0-20 to 0-40 or something like that. Unless of course you’ve ejected a rod, then it’s a new engine with the different oil.

Round 2:
An Oil Change Won't Fix GM's V8 Issues, New Lawsuit Says | Carscoops
This new class action, which names ten plaintiffs, challenges
GM’s proposed fix. Dealers have been instructed to inspect and replace the V8 engine if necessary. However, if the engine passes inspection, all the dealership needs to do is fill it with thicker 0W-40 oil, swap out the oil filter, and install a new oil cap. That’s it. No real changes to the design or the engine itself.
The plaintiffs argue that GM’s fixes are “egregiously inadequate,” adding that it will be replacing defective engines with “equally defective engines.” The also point out that the recall does not address the root cause of the problem, and GM hasn’t bothered redesigning the rod bearings or fixing the other issues that can lead to engine failures.
Additionally, it’s noted that most impacted owners will likely not be offered a new engine and will only receive the engine oil fix. In theory, this could leave them with V8s that are essentially ticking time bombs.
In short, all the plaintiffs claim they never would have bought their vehicles, or would have paid less for them, had they known about the engine problems lurking under the hood.
