Can anyone provide me with general info in the engine used on
the A1 Skyraider as used in Vietnam?

The A-1 ( formerly, AD, Attack-Douglas) used the Curtis-Wright
R-3350 engine.  18 cylinders, two rows of nine cylinders, displacement
obviously, 3350 cubic inches and a weight of 2779 pounds.  I don't
know if the A-1 ever used the turbo-compound version of the 3350, but
we did in the P2V Neptune.  Horsepower in the "plain" engine was
2800 and up to 3500 in the turbo-compound.  Other a/c using this engine
were the B-29, P2V, Connie, and DC-7.  The R-3350 was a very tempermental
engine that did not perform well for the airlines who flew at high cruise
speeds
most of the time.  At PanAm, we held onto our DC-6s much longer because
of the much more reliable R-2800.
