Default 8.1l injectors in a 2000 5.3

when i go to find them on ebay they are listed as 01-07. my truck is a 2000 and i'd like to know if they work in it. didnt know if maybe the plugs or fuel rail height was different on a 2000 vs a 2001 model truck.

gonna put a tsp 228r cam in it and eventually i'll slap a 6.0 in it with the same cam. think the 31s will be enough? (if they are a direct fit)

I have the 44's in my new 6.0, and they're perfect, but not cheap.

Assuming you're running a 5.3, what % are they running at WOT?

I know my stockies were tuned close to 100% WOT, so there was no need for me to use them on the new build. I still have them .... so little and cute, they'd make a nice necklace.

IDK about buying injectors from e-bay. I'd rather buy from someone here on the board, or even LS1 Tech, you know.. keep it in the family.

Just keep an eye on the boards, or post a WTB.
