Improvements in manufacturing brought the cost to produce each engine from $25,000 down to $8,500 and allowed the installed lifetime of the engine to be increased from 300 hours to as much as 1,000 hours for the less stressed powerplants.
I'm just doing the left side.
More specifically from a P-40E?
In one record, it was stated that the F-82 required 33 hours of maintenance for one hour of flight.
$14.85. Color would be good to.
1,600 hp (1,200 kW). Its reliability and well-mannered operation allowed it to operate at high rpm for extended periods.
Weight increases needed to accomplish this were minimal, with the result that all models were able to produce more than 1 hp/lb (1.6 kW/kg) at their takeoff rating. That gave different critical altitude ratings ranging from 8,000 to 26,000 feet (2,400 to 7,900 m). Allison continuously improved the engine during the war. More specifically from a P-40E? The benefits of a two-stage supercharger eventually became so clear that Allison did make some efforts in this direction.
Lots of photos too. Color would be good to.

What can be said for the Allison is that it made more power at less boost with a longer time between overhauls and the part count was nearly half that of the Merlin engine which facilitated mass production greatly.
Dan Whitney, author of Vees for Victory, the Story of the Allison V-1710, and a long time collector, historian and observer of Allison engines has personally inspected Gary’s engine and reviewed his observations and findings. There also was a high degree of commonality of parts throughout the series. The Allison V-1710 was one of the most important large U.S. aero engines, with over 70,000 engines produced from the time of the first in 1931 to the last in 1948. This approach allowed easy changes of the supercharger(s) and supercharger drive-gear ratio.
The main drawing would be, at this point, a copy of a copy of a copy, kind of thing, but most of the numbers are legible. The US Army had specified that the V-1710 was to be a single-stage supercharged engine and, if a higher altitude capability was desired, the aircraft could use their newly developed turbosupercharger as was featured in the P-37, P-38, and XP-39.
The engine was constructed around a basic power section from which different installation requirements could be met by fitting the appropriate Accessories Section at the rear and a tailored reduction gear for power output at the front. My email is jordanhluke (at) yahoo (dot) com.
the final V-1710-143/145(G6R/L) was rated for 2,300 hp (1,700 kW). There was no need to re-arrange the ignition wiring, firing order, or the oil and Glycol circuits to accommodate the direction of rotation.
If you bother to read my post, number 36 in this thread, you will know that my opinion is that V-1710 was able to do that job. If you know of a site, or want to email me, let me know! Although the early V-1710 powered P-39, P-40 and P-51A airplanes were limited to combat operations at a maximum of about 15,000 feet (4,600 m) they were available in comparatively large numbers and were the mainstay of some Allied Air Forces in all but the European theater of war.
The V-1710-C6 successfully completed the Army 150 hour Type Test on April 23, 1937 at 1,000 hp (750 kW), the first engine of any type to do so. Part of a 1/8 Allison/P-40 model project.
By 1944, the War Emergency Power rating on the P-38L was The Allison Division of General Motors began developing the ethylene glycol-cooled engine in 1929 to meet a US Army Air Corps need for a modern, 1,000 hp (750 kW), engine to fit into a new generation of streamlined bombers and fighters. When war materiel procurement agents from England asked North American Aviation to build the P-40 under license, NAA instead proposed their own improved aircraft design, using the V-1710 in their P-51A Mustang. The comparison is usually to the later, two-stage, versions of the Rolls-Royce Merlin built by Packard as the V-1650 and used in the P-51B Mustang and subsequent variants.
No intercooler, aftercooler, or backfire screen were incorporated into these two-stage V-1710 engines (except for the V-1710-119 used on the experimental P-51J, which had an aftercooler). The engine design benefited from the General Motors philosophy to build-in production and installation versatility.

Left/port side would be perfect. The G-series V-1710s installed on the F-82 E/F/G models had only anti-detonation injection to deal with these problems, and not surprisingly had severe reliability and maintenance problems. The V-1650 Merlin also replaced the V-1710 in the "F" series of the P-40. The main drawing would be, at this point, a copy of a copy of a copy, kind of thing, but most of the numbers are legible.
The Army Air Forces used the engine almost exclusively in the famed P-51 "Mustang", for it provided greatly improved high-altitude performance over the Allison V-1710 engine used in earlier series of the airplane. Lots of photos too.
Left/port side would be perfect.
But the opening post specifies "Was there any intrinsic design feature that precluded Allison engines from powering single engine fighters over Germany at 25000 feet" - and in any book that means the time period of mid/late 1943 until the VE day. The engine was then offered to aircraft manufacturers where it powered the Curtiss X/YP-37.
