I need schooling - old vs. new engines
There are compromises in EVERY production engine out there.
Absolutely. There is no perfect solution for anything. Completely agree.
Chrysler spent all their money on the G3 Hemi, which NA is less than impressive. I get that they were looking down the road to supercharging but that doesn’t change all the issues an NA Hemi has.
Almost 500 hp from an NA 6.4 and still get 25+ mpg is less than impressive? You must run in circles I can't fathom. Even a small 5.7 with no more than a cam swap is 450 hp or so, and still way more drivable than a similar 408 even though it is down on cubes. Heck, BP's biggest offering for a SB Mopar is down when compared to a stock 6.4, let alone the aftermarket one they are working to bring to market.
Maybe you run in the BB circles? Those certainly have something to bring to the table. Pretty sure a BB wedge head can keep up with a G3 Hemi head. But not everyone wants to put 500+ cid motors in their cars.
The only other circle I can think of that you might find the NA G3 less than impressive is drag racing. Seems like there has been plenty of success there, but I'm not watching so maybe you don't see them work well there?
Can you list for me "all the issues" an NA Hemi has? Not poking at you, just curious what those are.
Things that I can think of that a G3 Hemi added when compared to an LA/Magnum
1. Block doesn't get fragile at 500 hp.
2. OEM cask crank is good to 700+ hp ('09+)
3. OEM Cylinder heads that flow well (

4. Doesn't leak oil
5. COP
6. Tuned equal length runner intake
7. SRV (truck and 6.4)
8. VCT ('09+)
I get that things like #7 and #8 are less than useful for drag racing, and even something like the intake might be less than ideal for that. But in the world of driving a car on public roads they can be very helpful. And (I think) this thread isn't about a drag motor or it would be in the drag racing section.
