30K is a long away from your claim...and not remotely new off a bench fully accessorized and dyno'd to boot.
that was 7 years ago for an overpriced car, not the subject here anyways, the 55 has a blower.

i can find these all day long, 15k gets you a low mile car with impeccable maintenance and all problem areas addressed.
regardless the point is you can get a 500/almost 500 NA engine and a car for 10k. or you can enter the 21st century and go FI
Thats a 13 yo clapped out pos and isnt yours to boot.
ok and? you can drive it for 5 minutes, crash it into a wall, hit your head on the airbag and come to the realization FI is king. 9k well spent

You are forgetting stuff like the 6.0, 6.4, 6.2, 6.6, 7.3. Duty cycle. When I am towing 32 feet of trailer that is over 8000 lbs up Vantage I don't want a Turbo V6 or or smaller turbo. It makes a difference over time, the big V8 just isn't sweating yet or making all the heat under the hood. I use my truck to tow often, really that is all I do with it. The 6.0, 6.4 and 6.2 (GM, Mopar, Ford) are proven and will go 200,000 to 300,000 miles towing with less issue than I have seen from their smaller V8 and Turbo counterparts.

Although old, the 1uz in my GS400 has 80% of its torque available at 1800rpm. Idles & runs smoother than almost anything out there. It's faster than my parents dual charged xc60 T6, same freeway mpg, 345k mi on the GS & 28k mi on the Volvo. No idea if the Volvo will make it to 200k.
I’ll say this: the NA V-8 in the Tundra sounds great when you get on it. Better than any V-8 I’ve owned, which includes quite a few.
The uncorked Eco Boost in the Raptor sounds just awful. Trashy, uneven, economy car sound.
I had a guy get on one next to me just yesterday (something about my Mercedes makes pick up truck drivers floor their trucks next to me, not that it matters).
Lots of power. Sounds awful.

No, the 5.7L in the RAM make 395HP/410lb-ft.
And no, torque doesn't "stop being produced", the torque curve simply starts to come back down after peak torque. With the introduction of VCT, the torque curve has been broadened as well, coming on faster, and staying near peak longer.
If we are going to be comparing to forced induction offerings, the 6.2L in the TRX produces 702HP and 650lb-ft of torque.
Torque is twisting force, HP the rate at which work is being performed. You can apply torque while doing zero work.
simpler is BETTER aka NA engines. the move to smaller turbod engine is all about efficiency! looked at vids on the 5.0 in a F150 ford techs interviewed noted seeing few in for repairs + noted more costly repairs on eco boosted engines, so the longer you keep them the more it costs, eze choice IMO

Odd, you didn't mention you haven't owned the E55 since 2018 in QP's thread where, like in this thread, you dump on 392 owners
Did you spend "$$$$$$" in order to make this below claim possible?2EHA said:
Stock, the E55 is what, a mid to high 12 second car in the ~115Mph range? pretty much identical to a bone stock 392 car. On a tire with some weight reduction like the rear seats removed, a 392 can be into the 11's:

It seemed a bit odd for you to be dragging 392 owners with all this in context, but then your exchange with @UncleDave here makes that less so.
Now, I've only owned 4x 392 vehicles and driven several Hellcat 6.2L equipped ones (the pictures of which have all been posted on this site), but I also find this statement:
2EHA said:
Odd, as I've not found the 6.4L/392 lacking in the torque department, nor does the 0-60 time support that claim. Is the Trackhawk faster? Yes, but the 6.4L is more responsive out of the hole than the 6.2L Hellcat mill is, having driven both back-to-back multiple times. As soon as the supercharged HEMI makes boost though, it's over, it pulls much harder once wound up, as one would expect.

In my case, the simplicity (easy to work on) and the experience. We've had 5.7's at work for the last 10 years, I've watched them all rack up lots of mileage (approaching 200,000 miles now) with some less than "top shelf" maintenance and we've lost one to lifter failure out of the whole group, which is not bad IMHO, given how these have been operated.
Pushrod V8's are typically easier to work on (yes, the HEMI has 16 spark plugs, which is a PITA) and that, coupled with traditional port injection, makes it the perceived "safe" choice for many people. Given all the chatter on here about DI build-up, fuel dilution...etc, it's easy to see why avoiding that might seem attractive.
Now, you add DI to the V8, and that starts to change things, as noted with Ford and the 5.0L. If both options were DI, it would likely come down to which drives better, which may end up being the smaller displacement forced induction engine.

1488# payload and it's a base Titan S CC 4wd. Lower that I expected and it's going to cost me.
Good numbers on your truck and trailer.
no. you hit a wall past 500whp, after long tubes and pulley. you have to fight a blower that puts out nuclear reactor levels of heat. getting a 392 all motor to 500whp is $$$$$Odd, you didn't mention you haven't owned the E55 since 2018 in QP's thread where, like in this thread, you dump on 392 owners
Stock, the E55 is what, a mid to
if you throw in about 10 grand in an e55, much less than the amount to boost a 392 and then not blow it up, you’re at 700. or you could’ve just got a CTSV2 which is what sane people do.
at current prices the 392 is not the best performance for your dollar. many hurdles to jump over to get more performance out of them, the same story as every other NA build.

A local guy that has a YouTube channel decided to use his AMG 6.3 as a boat driving through a deep puddle.
He had less than 10K miles on the clock. It was a $85K car a year and a half old that the insurance company totaled it because, the hydro locked engine was $72K to replace. He bought another one and with in a year he got rid of it
Don't ever buy a used Mercedes or BMW without having a mechanic run a High level scan of the computer system. People dump them when they realize what all those expensive little red notes of electrical faults in the scanner mean to their wallets.

It's funny, but follow any F150 forum and it's actually the 6cyl turbo trucks that work hard towing daily that seem to last the longest. Not what you describe. Those wastegates need exercise. I have owned a 2009 5.4, 2013 5.0 and 2016 3.5 eco. 80k miles is amusing. The Eco has been Ford's max tow engine for 10 years now.
Ask around:

Whats not impressive is a twin turbo/ blown multivalve headed V8 that can only manage 500HP, when a couple of teenagers can slap together an NA 2 valve cam in block pushrod mill that makes the same if not better HP and torque using 75 year old tech.
On EB's I think the instances of premature timing chain and phaser issues have been disappointing.
The guys on the boating forum have had piston cracking problems towing in extreme heat with ecoboosts.

^^^ I have a theory.
there’s a lot of posting about ecoboosts running hot when towing. Now, granted, these may also be the same drivers who feel that towing heavy trailers should not interfere with their inherent right to climb steep grades at 5 over, as there seem to be some out there.
theory - on a big bore motor, there’s a lot of piston surface area, and there are larger cylinders, and more area exposed from piston to block and block to water jacket and water jacket to coolant. There’s all this surface area to keep heat from 1ATM of combustion out of the chamber into the coolant. But in say mine, it’s a smaller piston, cylinder wall, cooling jacket and exposure to coolant. Call it “half” the surface area, for the same amount of work. ive wondered if the physics simply can’t provide the heat transfer needed, even though the power is there.
this would also explain why Ford might keep the 3.5 around.... maybe it can get more heat out a little better?

The use case Im presenting is real and also extreme, AND the area Im talking about is the exact same hill used for J2807 certification. Davis Dam. In the summer ambient temps can start at 120.
On the Ecoboost ...ANY hotrod shop building a turbo mill for longevity would use very expensive forged pistons. Not aluminum hyperuetectics. This wouldn't not even be a question.
the reason they dont isnt so much cost as it is forged pistons need to expand and while cold will likely allow some blow by and leakage - this is a real problem from an EPA perspective which is why hyperutectics are typically remain tight with very little expansion and contraction.
The timing chain issue seems to a mix of bad part runs, long OCI's but maybe not.
