1) The LT4 engines didn't have the LT4 hotcam. They had the "regular" LT4 camshaft. Most people get this confused, but it's understandable.
2) Not exactly sure why they used 26# injectors, but the LT4's had the different heads and intake (like you said), which might account for it.
3) Keep in mind that the factory LT1 programming has the 1994-1997 24# injectors rated at 24.91#. Also keep in mind that factory 1993 LT1's used 22# injectors.
But yes, assuming your car is a 1994-1997, you'll be fine with stock injectors. I ran the hotcam (+ all boltons) for a few years on the factory fuel system without any problems, and I know many others have as well.
