Why? Variable valve timing, DOHC (for most?) aren't the lost primitive things
Is my 4G15T with cast iron block that outdated?
Most primitive engine in recently available vehicles

Anything with pushrods and port (only) fuel injection. Namely, GM and Chrysler V8 engines.

i once bought a 4.3 vortec base model silverado regular cab because i didn’t want to risk the newer 4.8 LS engine. Which, of course, turned out to be just about as reliable an engine as has ever been made, and blows the 4.3 out of the water in every respect.
Honda’s V6 dates(J series) itself back to 1996. It has been improved over time but is relatively primitive now.
It’s an interesting question. Maybe the Ford 6.2L V8 and it’s larger brother the 7.3 pushrod.
The Grumman LLV mail trucks still run Iron Dukes. Since they're constantly getting refurbished, they're like Ships of Theseus, and ageless.
The OHV Cavalier motor lasted until 2002!
This one is kind of primitive, with few modern things accepted (direct injection), but still has the now forgotten spirit of naturally aspirated fun VTEC machines. K20C2. It is the 2.0L Naturally aspirated engine offered in all Honda Civics after 2016. Definitely a dying breed.
Fun fact: a simple flash tune opens up 20-25 WHP. Add intake/exhaust mods into the mix, and 40-50 WHP over stock is very doable. Not bad for N/A. I guess direct injection ain't so bad after all...

The Honda HR-V has a SOHC non-DI engine with no turbos 
I think the Spark is also still port injection, but is DOHC
The V6 is all VCM now, so it doesn't count

Dang I forgot about the HR-V... That's still rocking the good old R18! Fun fact: performance wise and interior space wise and HR-V is very similar to 1st generation Honda CR-V. Vehicles just keep on growing...The Honda HR-V has a SOHC non-DI engine with no turbos

As for car engines...
VW 2.0 - The 2.0 and 2.5 are the only two VW engines I recommend for non-enthusiasts. As one poster already mentioned the Jetta had it until 2015.
Mitsubishi / Chrysler MIVEC 2.4 Liter - Started in 2005 here in the USA. They even used this engine in the 2020 Dodge Journey.
Toyota 1.5 L and 1.8L - The former was barely modified in 2007 and was used in the 2015 Yaris. The later started in certain versions of the 2001 Corolla and lasted all the way until 2016. They do have variable valve timing but that wasn't cutting edge compared to Honda who offered their own variation nearly a decade earlier.

I think they run the one after the iron duke. The 2.2l I4. Wasted spark ignition and port injection but still pushrod valve train.
The 4.3 was still SBC based till 2013. I don’t know if the di 4.3 is ls based.
While not vehicle based the small block Chevy has only been replaced by the LS in the last couple of years in industrial applications. They were putting turbos on 4.3, 305s and 350s in 2016 when I was working on installing generators. Even the 8.1 got upped to 8.8L and turbod.
Maybe but if it was discovered that a new vehicle had a flathead under the hood this place would go bonkers.
And that's why it is, and will likely remain, one of the best going today!
My very first new truck, at age 19, was a 1985 Chevy S-10 with an Iron Duke 4-cyl and 4-on-the-floor. It was unbelievably basic and had nary an issue while I owned it during my 4 years of USAF service. Sold it to my father on his Iowa farm, and he drove it for for 100,000 miles. In turn, he sold it to the neighbor farmer across the road from him. Then he drove the pants off it -- till it rusted out because of Iowa's winter salt.
Yes, the new 4.3 is LS-based
