Default Injector upgrade

Im running a 6.0 with an EPS cam, 218 intake 226 exhaust on a 114 LSA. I also added 243 heads, headers, and am running about 10.5-1. Need a recommendation regarding injectors. I have been told the stockers are borderline. How much do the stock 8.1 liter injectors flow and would they work well for me?

My setup is similar to yours. I just swapped to some LS7 injectors with spacers. They use the same connectors and should safely run a stock C6Z06 power.

Plus the injector values are already known for ease of tuning.

You confused me, you said something about a 6.0 and then you said something about a stock 8.1 liter injectors

what size motor do you have? 6.0 Liter right?

FIC injectors is a sponsor on here. they are good

first of all, check out www.rceng.com or RCEngineering if I cannot post the link. Check out their technical sizing page.

I would recommend 42# rated at 43.5psi (which gives you more breathing room) as you are naturally aspirated and should be under 550RWHP
NATURALLY ASPIRATED.

If i confused you with that lingo, and the pressures & ratings let me know.

My engine is a 6.0, lightly modded. I was considering adding stock 8.1 liter injectors as an upgrade as I have read they flow a little more than the 6.0's. I assumed they would be a direct swap in as well.

I have a set of green top 42lb injectors but was told tuning with them can be a pain, and that I may need an adapter harness and spacers to use them on my stock truck intake. Im pretty new to modding the LS motors, so maybe I am way off base.

I'm not familiar with the green tops.... those are the ford injectors?

the 42# racetronix injectors i had a long time ago worked great and little to no tuning
