Hello, got a few questions I'd like to get answered before jumping into my build. As you may recall I was going to put a lt1 in my 06 silverado but then I bought a 6.0. I have a 99 engine complete. Guy said it lost oil pressure. The motor is not locked up. I'll be completely rebuilding the engine with a fully forged 408 stroker set up. I have 317 heads that I am have ported, thinking about picking up am ls2 intake. Is 60lbs injectors enough? What other upgrades should Ido to my fuel system? I'm looking to get 650/700hp to the wheels. I have a p1sc procharger that I'll be slapping on it. I have everything ecept for the brackets Am better off buying the brackets from procharger or just making my own? Also plan to upgrade to the d1 later on. Also I'll be mating up a t56 trans. I know the 03-06 6.0 have a smaller crank flange allowing the ls t56 to bolt with no issue. I have an lt1 t56, I have been told that the 99-02 motor you can use the lt1 t56 trans with no issues. Is this true?

 

I don't think there is any way a T56 will live behind that in a truck but I love the idea.

 

I was thinking the same.

 

It's a level 5 rpm t56 so we will see! Lol

 

If its a built 56 it should do ok. However that P1 is gona be out of steam, doubt;'t you will make much boost, before you over spin it. You will also need more injector to get 700whp.

 

What injectors should I run? I'll be upgrading to the d1 next fall.
