LT1 injectors on 89 TPI?
I have discovered I have a leaky injector when I was deleting vats. I want to take care of it before it washes the rings out and gets in the oil cuz who knows how long the previous owners drove it like that. My question is can I run LT1 injectors without having to modify anything. I figured the injector bodies should be the same so mounting them in place shouldn't be a problem but are the injector plugs different? Also what's the flow rates on stock TPI injectors cuz the ones I want to get from a guy in the forsale section are 26 lb.

L98's and 92/93 LT1 are 22lb
94'+ LT1 are 24lb
All interchange but I don't think you can step up to 26's on a L98 without a retune

They will physically drop in. They are slightly shorter but not enough to make a difference. The connectors are the same.
You will need to tune a chip for the car with the new injectors. You can drive it with the stock chip but it will run pig rich and thus be down on power.
