In addition to the transition issues, I have wondered whether another part of the problem with the GP35 could have been that the 567 block had reached (or possibly surpassed) its practical limit. The same basic 16 cylinder block was good for 1350 hp in 1939, but with various "minor" upgrades (or maybe not-so-minor, depending on your point of view), had nearly doubled its output by 1963. Was 2500 hp too much to ask of sixteen 567 power assemblies?
Put another way: Didn't most GP35 rebuilds after the Dash-2 era include 645 power assemblies, rather than the 567s? Perhaps that could be an indicator that the railroads found the 567D3A block to be lacking in some respects (hope I got that prime mover model number right).
