The creator addresses the common question of why the 5.7L HEMI engine doesn't produce more power. He explains that Dodge effectively already created a more powerful version in the form of the 6.4L HEMI, then details the specific engineering upgrades (displacement, heads, camshaft, etc.) that differentiate the 6.4L from the 5.7L. He concludes by defining the 5.7L as a 'workhorse' engine and the 6.4L as the dedicated 'performance' engine, before asking the audience for their opinion.

Why doesn’t Dodge give the 5.7L HEMI more power? 🤔
Well, in a way, they already did. It’s called the 6.4L 392 HEMI.
The 392 wasn’t simply an overbored 5.7. SRT engineers gave it more displacement, better-flowing heads, a more aggressive cam, improved cooling and plenty of other upgrades to handle the extra performance.
So instead of pushing the 5.7 further, Dodge already had the 392 to fill that higher-performance role.

I keep hearing people say that Dodge should just give the 5.7 Hemi more power, and honestly, there's a reason why they don't. Because in a way, Dodge already did that, and it's called the 6.4 Hemi. And no, the 6.4 isn't just an overboard 5.7. There's a lot more that separates these two engines than displacement alone because the engineers at SRT basically took the Eagle 5.7 Hemi formula and optimized it for more performance. They did this by giving it more displacement, better flowing cylinder heads, a more aggressive camshaft, inactive intake manifold, better cooling, a forged steel crankshaft, piston oil squirters, and plenty of other upgrades. And the result was the 6.4 liter Apache three ninety two Hemi being born. And that's also a big reason why the 5.7 Hemi has made pretty much the same horsepower since 2009, because why would Dodge keep pushing the 5.7 when they have another engine that was specifically designed to make more power? The 5.7 was designed to be the workhorse affordable v eight, whereas the 6.4 was designed by SRT to be an all out performance v eight. But no, I want to hear from you guys. Do you think they should have gave the 5.7 Hemi more power, or do you agree with me and think that the 6.4 already does the job well? As always, I mention no hear your thoughts in the comments and follow for more.
