What about it, you automotive historians? What is the largest-displacement engine in a passenger vehicle ever? Can be any road-going or racing car, but not one of those off road mining truck monstrosities.
Pic for laughs:
I'm going to go with this,

For 1970 Cadillac stroked the V8 to 4.304 in (109.3 mm), increasing total displacement to 500 cu. in. (8.2L). At introduction it was rated at 400 hp (298 kW), SAE gross, and 550 lb-ft (857 N-m) of torque. For 1971 compression was reduced to 8.5:1, reducing power to 365 hp (gross) or 235 hp (175 kW) in the new SAE ratings. By 1976, its final year, it had fallen to 190 hp (141.7 kW). It remains the largest displacement regular-production passenger car engine ever offered by a US manufacturer.
Edit, found much larger
Quote » The Bugatti Type 41, better known as the Royale, is perhaps the most extreme luxury car ever built. It was enormous, with a 4300 mm (169.3 in) wheelbase and 6.4 m (21 ft) overall length. It weighed approximately 3175 kg (7000 lb) and used a massive 12.8 L (12763 cc/778 in³) straight-8 engine.

Nah, GM makes a 620 Big-Block
What was the displacement of the Cadillac V-16?

I will have to look up some exact models in my racing book collection, but racing cars between 1902-1915 had humongous engines.
The Ford 999 has a 4 cylinder of almost 1200 C.I. and there were Fiats that were bigger still.
The Allison airplane engine V12 was also sometimes used in dragsters in the 50's and 60's

x2. /thread. The only other thing that'd match it was the '55 Chevy with the same engine that went up on ebay a few months ago.
Rolls Royce Merlin Engine, 1649 cubic inches:
A Rolls Royce 'Special' with a 27 litre, 12 cylinder Merlin engine, as used in the famous World War II Spitfire fighter plane is the latest exhibit at the Haynes International Motor Museum at Sparkford in Somerset.
According to the previous owner, The Rolls Royce 'Special' Open 4 seater goes "as fast as you dare to drive it" and reputedly gives "the buzz of a lifetime", and stopping distances "need to be thought about well in advance".
Built on a 1928 Overland chassis from the Midlands, the Spitfire based Rolls-Royce Merlin aero engined car drives via a 4 speed pre-selector gearbox and then through twin chains to the live rear axle and runs on 20 inch artillery wheels with hydraulic brakes to the rear wheels only! The Merlin engined spitfire was of course instrumental in winning the Battle of Britain and was flown by the "brave few".
Sorry I can't locate any photos.

If we're looking pure displacement to the wheels, this wins so far....
4 engines at 464 c.i. each = 1856 c.i. total
1856 c.i. = 30.4144 L...which beats the tar out of that 27L Merlin by a whopping 3L (3L is the size of my old Ranger's V6 engine just for a size comparison).
Now, if we're talking HP to the wheels, that something totally different and out of my realm!!!
Jay Leno's Tank car
This engine is an AV-1790-5B and it's 1792 cu. in. It has overhead cams and Hemi heads. Since it was designed to move a tank, it puts out 810 hp and makes 1560 ft.-lb. of torque. But you can't just hit the local neighborhood NAPA store for replacement parts on one of these.
Although I would hardly call this a 'car'
