And the air racing guys hate, HATE HATE the folks who stick 'em in their unlimited hydroplanes, because they trash the engines and they're no longer usuable as rebuilds for the P51's they're tring to keep in the air...

You're in luck. The T 44 WILD HORSES is for sale and it will only set you back $225,000...

Yes, the Merlin is a V12...

The Rolls-Royce Merlin is a British liquid-cooled V-12 piston aero engine of 27-litres (1,650 cu in) capacity. Rolls-Royce designed the engine and first ran it in 1933 as a private venture. Initially known as the PV-12, it was later called Merlin
Was the top dog of aircraft engines for a very few years. Then came The Allison V-1710 aircraft engine designed and produced by the Allison Engine Company was the only US-developed V-12 liquid-cooled engine to see service during World War II. Versions with a turbocharger gave excellent performance at high altitude in the twin-engined Lockheed P-38 Lightning,
also the radials which grew to enormous sizes the Pratt&Whitney 4360 was quite successful with 28 cylinders arranged in 4 staggered rows with 3000+ hp and around 3500 hp in later versions. Lycoming also built and tested a 36 cylinder 7755, A 5000+ hp behemoth with a displacement of 7755 cubic inches weighed in around 6000lbs.
Ans since we started talking somewhere in this thread about engines being used in marine applications it is worth mentioning the aluminum Bentley marine 56 cylinder radial
Getting back to "V" engines Chrysler developed a unique v16 2200 hp engine that took its power from the center of the engine instead of either end this was also Chrysler's first Hemi

The Brits certainly have some obsessions for Merlin powered cars:

I wonder if there were a lot of those engines left over there after WWII?

Not sure how this thread swapped over from B-24 engines to Merlins? There were some 19 000 Liberators built, and around 13 000 C-47 Dakotas which means a total of 102 000 PWA R1830 engines fitted to new aircraft of these types alone. There were a total of 173 618 of these engines built and there are still a number of DC-3's flying, and both new and second-hand spares are freely available.
