Re: PC: Like Like Proto 2000 GP20

["Bill K" <pontiac@xxxxxxxxxxxxxx>]

This month's Diesel Era has an article on GP20's.  No PC pics, although at
least two NYC and one Conrail are shown - One thing I found out from it was
that at the time the turbo was removed it also got 645 power assemblies,
similar to what NYS&W has done with their GP18's.  As a result the units
remained 2000 horsepower - For those of you who may not know what that
means, as I understand it it would be like putting big-valve heads and a 4
barrel on your 2-barrel 350 - same block and pistons, new heads and top
end.  Makes sense to me, since the early EMD turbo has a rep for being
trouble prone -
