>damn good indicator of how well engineered an engine is
For fuck's sake user stop listening to carthrottle. Let's take an LS3 and a Coyote. Both made around 430 horse in the same time period, early 2010s. The LS3 is 6.2L. The Coyote is 5L. Obviously the Coyote's better, right? Not necessarily. The LS3 was lighter. The LS3 had a slightly lower center of gravity. The LS3 had a flatter torque curve. To be fair to the Coyote, it revved 1000 RPM higher.
Which was the clearly better engineered engine here?
Or let's talk about workhorses. The Loma 2.3, for instance. Sub 100 hp out of a 2.3. WOW THAT'S FUCKING SHIT AMIRITE
It's a workhorse engine. Made to last many hundreds of thousands of miles and get semi-decent gas mileage. Why would it be tuned to make power?
V6 in 2017 still making under 300 hp
Oh and the LS3 was physically smaller than the Coyote by a couple inches.
the Coyote is obviously the better engine with more potential
LS engines are mediocre at best

>headers, a cam and a tune will put you 250-270, and a +t is ease
I’ve never understood why this was allowed for a modern “performance car” the torque curve isn’t even great

it was the base model, the TTs produced 300hp, which every by today's standards isn't slow...that is, unless you're OP
Displacement volume isn't the same as the space you engine takes up.
How is revving 1000rpm higher to make the same power a positive?
More revs to play with means you can gear lower.
>implying how well an engine is engineered has anything to do with drivetrain losses
It's more like a damn good indicator of how low or high an engine revs. The highest hp/l production engines are all super oversquare motorcycle engines that rev to an F1-tier 16,000RPM, and can and do put out F1-tier hp/l figures with a little ECU tuning, head work, and forced induction. These machines, despite their benchracer numbers, are basically being lugged at city speeds. Crack open the throttle on an R6 and...wait. Without an extra short first it's not going anywhere for a few seconds. And first is tall because circuit racers need to be in the powerband for slow corners, which are still 40-50mph. Those engines also have solid lifters and need them manually checked and adjusted every couple years, or every other race.
An engine tuned for pedestrian use will be built and tuned for a lower powerband, and lower revs if need be, and have a worse hp/l figure. Also can't forget the head that flows less air because the designers wanted to meet fuel efficiency targets for marketability and CAFE shit.
