Last week i swapped out my 5.3l for a LQ9 6.0l punched out to a 6.2l w/ factory LS3 pistons, rods & rings, And had the rotating assembly balanced, I used the same camshaft and injectors that i had in the 5.3l, After doing some fine tuning on the fuel system and timing This thing is crazy fast, Runs like the 5.3l did on the spray..
I'm wondering if my injectors are enough for this application and if not what size would you recommend.. I don't know how it could run any better than it does now.. wow..!

I need to update my profile after the swap but anyway I'm running 36lb injectors and a Lingenfelter LS1 R&D camshaft.. 500/218

 

Good to hear. Which intake are you running?

 

Sounds beast man. Im guessing your running a 2007-2013 truck intake?

If you plan on spraying I would get some 60lbs and have some extra room.

 

What does injectors have to do with spraying? I doubt he's going to be using a dry shot...

Do you have your own tuning software? If so check the injector duty cycle and that will tell you where you're at as far as needing more injector. IMO, 60lb'ers are way to much for your application.

I use LS3 injectors (42lbs) in my 6.0 H/C set up. I went from flex fuel injectors to that. Flex fuel injectors are 34-36... Cant remember but I was 90-95% on those. I put in the LS3 42lb injectors and now I'm 70-72% max.

You have a lot smaller cam so you'll probably be fine with the 36lb injectors

 

I have the stock Intake manifold w/ a 85mm throttle body that seems to give it some awsome low end w/ a stock converter, it will roast the tires..
I tuned it with a jet DST Tuner.. Its all i have for now..

This cam really seems to pull like gang busters from 3k to 6k
So if the injectors are not quite enough could be I'm losing some top end hp.. If so I'm not able to tell..

I don't have a wideband just a scanner that i can look at all the sensor and fuel trims..
I have a wet shot NOS system I had on the 5.3l and haven't sprayed this motor yet.. making sure i get all the bugs out first but i can just image what it may do on this motor.. wow

Thanks Guys..
