Default LS1 inj in an LT1

I'm sure this has been asked, but you can put LS1 injectors in an LT1. Plug looks identical. Are both the same impedence?

I think I read something one time that said they will work but flow less than a LT1 injector..

I've got the 28's, but have never heard a positive answer to them working. When you buy aftermarket injectors, they say they fit LT1's, LS1's, Fords, and more. If thats true then I dont see why they wouldnt work.

Yes sir, I have personally put them in and ran them in a LT1 F-body.

They work! And the 28's are a good upgrade.
