Vengeance IIIs modified as testbeds for R-3350-37 engines for the B-29 Superfortress. Only five built.

The Wright R-3350 "Cyclone" was one of the most powerful radial aircraft engines produced in the United States. The first R-3350 was run in May 1937, and later versions of this engine remained in production into the 1950s.

Thousands were built to power both military and commercial aircraft during this time. Its first major military use was in the Boeing B-29 during World War II. Subsequent versions were used in the C-119, C-121, A-1 Skyraider, and several Navy and commercial aircraft.

The R-3350 is a twin row, supercharged, air-cooled, radial engine with 18 cylinders and a displacement of 3,350 cubic inches. Horsepower ranges from 2,200 to over 2,800, depending on the model.
