Im doing an LS1/Cam swap into my 06 gmc that has all bolt ons but I am running the truck intake for torque cause I have a crew cab...My truck injectors I found out arent going to work so which step up should I change to? A friend told me 28.8 LS1 injectors would work but I have to change the clip on them or something, if you have what I need let me know!

 

Why wouldnt your injectors work? I put down 300+ with the stock 24# injectors.

 

what size cam ?

 

It's the 216/220 .525/.532 114lsa comp cam, he said it would be right at maxing out the stock injectors. He tuned my truck for them I think I just need to double check and see what I need to do. I ran the same cam in my 5.3 and I know the ls1 injectors max out at around or above 400 somewhere I've heard

 

i have ls1 injectors
$100 shipped Orings are included and in good shape!!
pm me

 

Are these 28.8s or the smaller ones? Where do I get the clips and whatever else I need to make em work on the truck intake?

 

I have the ls1 injectors and the clips PM me a price and I can get you some pics tonight.

 

I've got some stock ly6 6.0 truck injectors, only about 5k miles on them. Lemme know if you're interested. They're somewhere in the low-mid 30# range.

 

I have a set of stock LQ9 injectors. $45 shipped.

 

I thought you were going turbo? If so, you are going to need at least 42's. And if you aren't flex fuel, probably a 250gph fuel pump or at least a voltage booster on the stock one to support a turbo.
