I'm new to this site but I actually joined to offer a line of ALL Chevy motors. I have from 4.8 to 8.1 for sale right now wired to meet your needs (Yes, I have LQ9 too). I have LS1 intakes oil pans and injectors to swap over to fit your application (I can run E-85 fuel if you would like too). I build the harnesses to run the intake system either way so you don't have to make that decision until your making the test fit. The harness will have relays and fuss blocks also so no need to add another system to this one. I can add or remove what you need in the harness just request it and I'll see if we can make happen. Price range on mileage please pm me with request or text me @ 479-236-0625 Matt
