I wonder why they never attempted to propel the P-38 with P&W R2800 radial engines?...
Grumman proposed a V-1710-powered twin

Drawing and/or details about it?
Thanks in advance
BTW, was this V-1710 a previous proposal to the XF5F?

joncarrfarrelly said:While of greater displacement the P&W R-2800 is actually smaller in diameter than the Wright R-2600 and
the fuselage shape has as much to do with the P-47's ancestry as it does the engine and turbo installation.
Stargazer2006 said:Probably so... but the ancestry of the P-47 was made solely of radial engines! Not a single inline design at Seversky... Like the Grummans or the Brewster Buffalo, the Severskys had a barrel-like shape, very wide at the front and narrowing dramatically beyond the cockpit... So probably the type of engine used MUST have had its importance in the general lines of the Thunderbolt...
I believe you mean "handed engines". I don't see why not as it's primarily a change of gearbox, though I seem to rememeber that contra-props on the R2800 were one variation tested on the XP-47J.XB-70 Guy said:Wondering: Could they have counter-rotated the props (crankshafts) of the R-2800s if used. I know the Allisons had counter-rotation...
