The Siemens 60's will meet your goals if you plan on running pump gas. Whatever you buy just make sure they aren't knock offs and data is available for them.

42s are good to 550 ish. get 60s for a little more room to grow. or if you have plans of 800 go to the 80s

I might pick some up or just wait a few years tell I need them idk yet. I'm only planning to run 5-6lbs of boost to start which should put me around 500rwhp. The 42's and and racetronix pump should do that no problem....

If you already have the 42s then you could just use them until you get the car dyno tuned. if you find out your're running out of injector at that power level, just swap them out for a set of 60s...On the other hand, if you're yet to buy injectors, then I'll advise you go with the 60s and be done with it...I wouldn't be surprised if you end up being over 95% duty cycle with the 42s though....

I ran 600 rwhp on LS9 52lbs injectors without maxing them out. Data is not an issue with them which makes them easy to use. I would sell them cheap if you need them. Used for about 2000 miles.

Do ls9 injectors go right on an ls1 with no problems? Easy to tune them? If so I'm interested!

Tuning would be easy as all data is available. I'm not sure about the fit. I'm sure someone here would know. I believe they might require a spacer but you will have to find out for sure.

I have some 60's that I'm running that I'll sell you. They fit into the factory rails no problems, hell, I'll even give you my tune so you can just copy the data. I've got to move up to 80s.
