Any who has upgraded to the Lt4 fuel injectors, they come with a bag of hardware. Is any of this hardware applicable to the LT1, besides the clips? All of the plastic bushings and rubber washers were not on the original LT1 injectors, or am I missing something?

Your missing something.... there is some white bushings on the lt1 injectors. Sometimes they stick on the head and don’t come off with injectors

Look really good! Here is a pic with it in the head and without it.

Great pics, don't need much more proof than that. I used a plastic dowel to tap on my heads, all hard steel. I don't get why they were not on my, car had 3k miles on when I got it, so who knows. That's the only reason I questioned it in the first place, not being on originals. I will be using them for installation. Thanks for the pics.

Why are you putting LT4 injectors on? Will that alone boost HP? Are there other requirements that must accompany (fuel pump)?

Being installed to increase fuel delivery for newly installed supercharger and to add E85 capability. To get fuel benefit of the injectors you need to also install high pressure fuel pump and low pressure fuel pump. I added a voltage booster to the low side fuel pump for good measures.
