how much hp will 42lb injectors be good for??

I'm putting some 42lb injectors on a D1SC LS1 and I wanted to see how much hp I can expect to get out of those...The car already has a Walbro in-tank... Any help would be appreciated...

I hade 531 hp and 530something tq with 42#er's and a single inline 255. It was at 100% and was a bad scene. If u can stick with 500 hp ull be in good shape. If u plan on goin over that at some point then juet get 60's. That is what I have in there now. They work great. GL man
