Are you sure you don't mean 6-71 and 8V-71?

Enterprise DSQ-38 diesel. 8-cylinder, 16"bore, up to 420rpm.
Don't know if they are still around, but I worked on bigger & smaller, but we has some DSQ-38's that would run & run for days...... as long as we had fuel.
Have had some good luck on 16-cylinder locomotive engines too. Racked up decent years, hours of use.

Any Ferrari V12, they never built a bad one.
Nothing sings a siren song like a V12 Ferrari on its cams inhaling threw a stack of Weber carburetors.
Oh and Jag I6.
I love I6's, perfect engines really.

Actually they were very good engines, although the 354 ci was much more prevalent for industrial/marine use. They did have their downside though, the carburators and dual point ignition system was a maintainence nightmare. I had a friend who converted one to electronic ignition and eliminated most of the problems.
The one engine I haven't seen posted is the Chrysler flathead 6, probably the most simple, problem-free engine ever. I still have two, with one still seeing regular service. The industrial version (Crown) had sodium filled valve stems and quite honestly I think it is going to outlive me. I know of at least a dozen of these engines locally that still see regular service, they are mounted to 4" Hale fire pumps, WWII surplus!
There are a plethora of diesel engines that ran for thousands of hours, the DD 6-71 was probably the most diversified application engine ever produced, I now wear hearing-aids thanks to one.

It's really not hard to make 'hp/L', since hp is only a multiplication factor of torque, all one needs to do is tune an engine to most efficiently make torque at as high an RPM as possible. It can be entirely useless at any RPM below 6500-7000, and still make a hp/L record. In fact, that's exactly why Honda had to stroke it out (F22C) for the AP2
Quote:
Highest specific output of a piston engine goes to Renault's 1.5 litre Turbo used in the 1986 F1 season. In qualifying trim, power could be boosted all the way to 1,500bhp, giving amagical 1,000bhp/litre, although in the races, they ran at around 800bhp (a "mere" 533bhp/litre).
Some natural aspirated examples:
RC car engine -7.7cc, 5hp @ 649hp/L !!!
Yamaha YZF600 88hp, 600cc @ 146/hp/L
Suzuki 1.3L 163hp @ 125 hp/L
BMW S1000RR ~200+hp/L
Ferrari Italia 458 etc etc

Honda D-Series. Reliable, efficient and rev-happy.
for big block gas pigs the Ford 460 is a tough motor...we had two on our farm go to 300K and and another one with well over 220k when the speedo broke about ten yrs ago. This has been with little maintance other than filter and oil changes. The engine blocks just go forever.

And Jack Brabham won the 1966 F1 World Championship with the Repco-Brabham V8 that was a (heavily) reworked aluminum 215 Buick.

The derivatives of the Buick Alloy V8 have been quite good, including the Rover V8 and the 3800 V6. Of course, I speak of the long block assembly only, not anything bolted to it

...and more of topic...sorry, I had a 1979 MotoSki Super Sonic with a 340 (heavily modified) that made 96hp @ 12500rpm - 282hp/L. Stock it made around 200hp/L. 1985 YZ80 dirt bike was in around 225hp/L...gotta love 2 strokes!

Rocketdyne F-1 (to the moon); Space Shuttle Main engine; Packard Twelve (amooth, torque, quiet); small block Chevrolet (set the standard); Oldsmobile OHV; Deutz air-cooled Diesel; Cooper-Bessemer W-330 series (come on, 8000 HP and 80,000 hours at full load between overhauls? that's great!); Solar gas turbine; GE Series 90 (world record thrust of 120,000 poounds);the Watt steam engine; really there is a huge list of great engines, many of which have industrial applications and are not in the public eye. There are many subclassifications: best engineering; best quality; longest life; most rugged; most cost-effective; most efficient; most specific power output; largest; most consequential; the list goes on. The most manufactured may be the Briggs&Stratton lawnmower engine. Fun topic!

Incorrect, it was the Duesenburg I8 back in 1927 if I remember the year correctly. 320hp in supercharged trim, and much higher in some specs.

Another very durable Ford engine is the 3.0 Vulcan. We had one in a 91 Ranger that had 354K when it was sold. The valve covers were never removed. As my habit is, we did 10K OCIs and the engine ran as good as when it was first purchased.
" it was the Duesenburg I8 back in 1927" but who could afford one? the Duesy was not an V8. it was a straight 8. and was SOHC, DOHC. at 420 ci. the chrysler 331 ci was a push rod engine. my point is at that time chrysler was the first available american engine in the 50s to make 300 hp. the duessy is in a totally different class. the 55 300 sold 1,725. the dussy model A-650, model X-13, Y-1. if you had a duesy next to a 55 300 and told me i could have one of them, ill take the Deusy. like i said BEST in the eye of the beholder.
