This document is for the LT1 crate engine. Even if they used the same new cam phaser for stock LT1 Camaro engine builds from 2022, the probabilities of why GM used a new part is 99% that it's merely a cheaper component to save some cost and only 1% that someone in GM engineering still had the irresistible spark and the irrepressible grit to push a better (more powerful) design through.

Okay, why am I saying this?

- one, there has been no official Camaro development team since 2019, just a few caretakers to oversee manufacturing and the parts bin additions that must have already been in the pipeline from or before 2019;

- two, there have been zero reports of any widespread cam phaser issues, unlike, say, the LT4 oil pump or the A8 transmission shudder issue, so they had no obvious business imperative to seek alternatives;

- three, if they improve anything powerwise, they have to recertify and re-emission the car, which costs $$$$, and considering how little they invested into even the 2024 farewell edition (existing parts, a new paint color, vinyl and a cheap ass new badge), this is very unlikely.

All conjecture of course, and I'd be the happiest to learn that this was the 1% case, not the 99%, if someone has actual and verified information.
