Secondly, I think you may be confusing the abbreviation DaveReidUK used for the aeroplane (Vought 326) with the US terminology for the engines (e.g. V1710).
Certainly surprised that the diameters would be similar - would have thought another couple of pots per row would make quite difference! The only time I've seen either engine close up out of an airframe was a part-sectioned R-4360 at a museum in the US. I was quite surprised how relatively small it seemed compared with what I'd imagined!
Sorry, I meant to refer to the V-326 in the same way as Dave, as the aircraft type.
