LS1 Injectors in LT1?? I have a 1998 Stock Ws6.. and a 1994 Z28 355CI, Ported and polished heads, Manley valves, 3 angle valve job, 1.6RRs, Cam, and Spring set.. The camaro has a bad miss under load.. my question is.. will the LS1 injectors work on the LT1? I might add the Camaro has stock Tune and injectors.
Work? Yes. Be right without tweaknig? No.
LS1 fuel pressure is rated at ~4 bar (59 psi). LT1 fuel pressure is rated at ~3 bar (43.5 psi). So a 28 lb/hr @ 59 psi injector will spray significantly less at 43 psi. You'll either need to raise the fuel pressure on the LT1, or change the PCM for the scaling factor (probably to about 20-22 lb/hr).

Well, sounds like it'd be worth a shot to try it out and see if the injectors change it. 
I don't think having them in 'short-term' will hurt anything. I've known guys to stick 20 lb/hr injectors in their LT1s with no ill effects (other than their LTrims going to 160 while the PCM tries to flow more fuel - but that's another story...).
Give it a try, I'd say, and see if your miss goes away. Have you checked fuel pressure?
