Vega took a B-17E and substituted Allison V-1710s to see if they could be used if there was a Wright R-1820 supply problem. As far as I know only one was converted. It was designated the XB-38. One B-29 was also converted to water cooled engines and designated XB-39.

A dramatic view of the XB-39. Starting life as the first YB-29 delivered to the United States Army Air Forces, it was sent in November 1943 to the Fisher Body Aircraft Development Section of General Motors to be converted to use Allison V-3420-17 liquid-cooled W24 (twin-V12, common crankcase) inline engines.
