Largest displacement now / ever

[ctechbob]

My first car, a 1983 Camaro Berlinetta with the ohh so awesome 5.0 Liter.

I think every car I've had since then has had a smaller, more powerful motor (Except for my 91 Miata).

Last of my Chevelles had the SB Chevy 400cui 6.6L
Owned (2) Ford 302cui 5.0 - (best engines I ever owned.)

Fastest thing I ever rode in was a buddies Mercury Cougar with the 429cui engine he had source from a Ford. I had to change pants after that ride (pinned to the seat).

What is crazy , now we have a Honda 1.5 tiny GDI-T engine that has 160mph on the dash. Many of the fuel injected cars of today , I am certain could out run a lot of the older big heavy bodied classic cars from the 60s-70s.

Porsche eventually stopped at 3.0l in the latter stages of the 944's life. It started with a 2.5l four.

Yes.

But my understanding was @nleksan was listing the largest displacement engines he had personally owned in various engine configurations.

7.4. GMC Suburban from 80s. So unimpressive…

Smallest 1.6 VTEC 95 Civic.

YES, after about 1972 - 1973 all the Big Three auto makers were forced by (good old/NOT) Uncle Sam, EPA and the auto insurance companies to strangle down nearly all engines they put out. It still took Chrysler/Plymouth/Dodge a few years to comply. They were still sneaking out some high horse engines for a while longer.

So all of the engines eventually turned into what was known as "Smog Era" engines. The new unleaded fuel and the things that were done to de-tune engines really smothered the horsepower to near nothing on lots of cars and trucks.

It took until some time in the late 1980s to early 1990s till the automakers started to figure how to put more horses back into what they were making. Fuel injection and computer control became the savior for auto enthusiast..... We pretty much got it all now. If one want some high horses you can find them plenty places these days.

The 472cid put out over 320 horses. Should have pushed it nicely.

It was a comfortable cruiser. My father in law was a better accountant than I was a mechanic at the time. He got the better of the deal. It was also his last Cadillac.

I've had two Chevy 350s; a 1971 G-20 Chevy Sportvan with a Quadrajet and a 1974 C-10 with a Rochester 2 bbl.

 

[WeyounDS9]

Largest is now and ever 5.6 Liter V8 in my Nissan Armada and this engines predeccessor in my 2008 Pathfinder also 5.6 L V8.
Smallest was 2.0 liter 4 cyl in a Sabb 900

 

[Snagglefoot]

Currently have a 6.0 Chevy making 350 net horsepower.

I drove a ‘77 Cadillac with a 7L (425 cid) for a couple of years. Only rated at 180 hp but loads of torque. It had posi and would easily leave two black stripes on the pavement.

Ah, the LG4 V-8, cranking out a whopping 155 HP through its tiny valves, small cylinder head area, Q-jet electronic carb and two into one catalytic converter choked exhaust system….

 

[Snagglefoot]

My Uncle had a brand new Oldsmobile Delta 88 with a Rocket 455 with 210 HP but gobs of torque. In those days it was common to tow a small travel trailer with a four door sedan. I have a Polaroid picture of the engine (somewhere ).

 

[Snagglefoot]

Of course the topic is also about torque. Prior to changing from gross to net HP, those 454 Chevys, and 455 BOP’s we’re making 500 ft lbs, but by 1974 the net rating, with lower compression, resulted in torque ratings of around 350 ft lbs. Still, peak torque was at a low rpm like less than 2500 rpm. Comparatively my 6.0 makes 383 ft lbs but at 4500 rpm.

Yeah, my 6.4L makes 475lb-ft, but it's at 4,200 RPM. The dyno charts look pretty good for them though, lots of toque down just off idle.

I have a great deal of experience with the 5.0 L LG4

 

[MotoGuzzi]

Largest was a 440 cid in a 1969 Chrysler 300 convertible. Currently have a 6.4L(392) in a 2019 Charger Scatpack
