Lmao, cat blocks, crank, pistons, cam, head, valve train, gear train and most have stock Cat ecm. They have started using the custom rods so they can run C18 pistons with C15 cranks. That’s the C17 that Rig Wrench was talking about. The long CRANK stroke is what increases dwell time at TDC. That is why the C18 doesn’t like 3000+ RPM that IT WAS NEVER INTENDED TO RUN. I know this because that’s how I got my C18 crank. So I guess if you consider swapping rods “threw almost all stock Cat parts away” a major swap then you are correct. What your too stupid to understand is almost all of the pullers have ditched the stock fuel system. Not because it’s bad but it limits flow when your going for 3-4 times the designed HP.
Keep in mind you said before you had custom injectors for your truck. I guess that could be considered junking all the Volvo parts? And you still only make the same power as a stock cat with a tune.
Now the ones that are junk are the DT466, guys think they’re amazing engines because the pro stock tractors run them. What they don’t realize is NONE of the parts are IH. Hypermax block, custom crank, pistons head is solid. There are no IH parts on them.
