Yes these injectors fit the 04 silverado fuel rail system as well physically, however I would have to see which plug you have, they may require the harness adapter to actually plug in, but that only runs @30 or so through summit. It is common on 4th gen camaros running ls3 or similar injectors. not a huge deal. let me now which ones your are interested in.

 

LMAO
No mistakes foreseen in the future for the exhaust my friend, but pm me if interested.

 

Sorry guys for the late replies, We got the engine out and tore down and found some things that were disturbing, like a very overbored block for the piston installed, and a block that will now only be good for a .080 piston, that is not available readily on the shelf for a 4.125 stroke crank. So I have been a little frustrated in trying to figure out what and how I plan to fix this issue. But that is behind me now, Gonna buy a new block.
Got a crazy question, but has anyone ported a LSXRT Fast intake to work with a LS3 rectangle port head?
