The end is near...

Who said they were “complete trash”? They are like every other NA Hemi ever built. They are junk NA unless you have the balls to wind them up. It doesn‘t matter if it’s a 392, 426, GIII or even a Pro Stock “hemi”. They require big RPM a to be competitive.

The LS, which is just as ugly as the GIII is a FAR BETTER engine to start with.

RPM is horsepower. To make horsepower with a Hemi you need big RPM.

Simple as that. NA compared to a wedge they can’t compete.
When I hear "turd" that's what I think, worthless garbage. I understand the poor cylinder filling and excessive unwanted overlap flow at lower RPM due to the valve orientation. Is what you're saying here about the LS being a better starting point something you've come to conclude yourself or are there others who agree with you from experience? Also what about the much tighter included valve angle on the G3 compared to all the other Hemi engines, would that not aid in keeping the air/fuel going into the cylinders instead of out the exhaust? Serious questions, I'm trying to learn and resources are scarce. I might email Darin Morgan and/or BES about it because it's really got me curious now.
Do you think it can’t be done? Because it can.
I think it can too, but with stock dished pistons down .050" at TDC that can provide 9.5:1 compression at best? The guy with the Hemi truck didn't mention anything about changing pistons. Then even if the lower compression can be overcome you'll end up spending way more on heads and likely valvetrain which you might say is besides the point but that's still one place the G3 has an advantage. If you disagree please explain how I'm wrong don't just shoot a red X at me.
