Re: [CBQ] FT Lettering

Bill,

Thanks for the actual wording. Obviously, the unit has a replacement engine. 
The original engines, I believe, were 567 or 567A. I think the “A” model may 
have come out after WWII. The 567 received gradual improvements to correct 
problems and to improve performance, reliability and horsepower over the years, 
culminating in the 567D3A in the GP35 model. Amazing that the basic engine was 
able to be upgraded form 1350 hp all the way to 2500 hp. With the 40 series, 
the 645 model was introduced. Some of those original FT crankshafts were 
remanufactured and installed in 40 series models at 3000 hp. You might say that 
the crankshaft was somewhat over designed originally.
