I will be needing a small upgrade and I see 28# Z06 injectors turn up pretty cheap. Will these work on a LT1?

 

Dont buy them. Little secret: LS1's have more fuel pressure so in turn if you put them in your LT1 which has lower fuel pressure. They will be just like what you have. Thats why alot of guys turn the fuel pressure up but it also makes your pump work harder. If upu want bigger injectors, go with 30 lbs SVO's.
