I had 30lb SVO injectors which flowed on a LS1 about 36-37. If you have 36lb SVO injectors i think they flow 42+lb atleast, not sure but someone will chime in hopefully. I would upgrade the fuel pump as well since you already have H/C with a 150 shot you are at the fuel pumps limits if not past.

if its a wet shot, you dont need to change anything for the injectors..
if its a dry shot...A 36lb injector might be pushing it..

either way.. you need to upgrade the fuel pump.

i knew that

i was under the impression that the injector size would not matte because i have a wet system, but had a conversation with my friend that just would not accept that.

then i was called brave in another thread here, so i decided to check out if i was wrong after all

thanks for the answers

Brave for shooting a 150 on an LS1? You must of ran across a newbie.

I shoot 150 on 6 cyl engines.

to be straight forward...
a 150 shot on a stock bottom end will live all day long assuming you dont cause detonation from too much timing for your setup...
200 starts to get iffy...thats when you start to break stuff in the bottom end...

guys are doing more with no immediate issues...but its borrowed time for the most part..
and everybody doing a 200 or bigger, will be replacing a motor sooner than originally planned(unless they are trying to see how much they can spray to blow it up so that they can buy the stroker they wanted to buy anyways..LOL)

You will be fine with the setup that you have. on a wet kit your nor relying on the injectors themselves to introduce the extra fuel, that is done of course by the fuel solenoid. Now if it was a dry system then yes you would need to upgrade them.
