What does a wet shot have to do with it. With the upgraded fuel pump and upgraded injectors, you could run either wet or dry kit.

30# will be fine (I'm running them in my car, both when I was cam-only and with the new motor). If you're running a wet shot, upgrade the fuel pump also. That's all you need. 42# injectors on a cam only car isn't the right approach, IMO. Let alone 60.

First of all, all injectors are rated at 43.5 psi. Therefore the injectors flow 30# at that pressure. The LS1 runs a high fuel pressure of 58-61 psi. This effectively makes these injectors flow 36#. This is enough fuel for hp at the flywheel of over 610. Each lb is good for about 17 HP plus upward rating adjustments for the LS1 pressure.
Shaprio... sometimes the larger injectors can be hell to tune at idle.

JamMasterJ: 6 in one hand half Dozen in the other. I understand and Agree totaly with your statement. But These new 60's are the real deal and very Easy to get a good Idle.Would i recommend 50's or 55's to someone only running NOS, no but i would recomend the 60's to anyone that plans on keeping there car and do plan on more mods later on down the road. My statement about larger injectors was in general about cost if buying new why buy 30 when you can get 42's for about thew same price,Mods,NOS,Boost as we all know becomes Addictive and i can think of a whole lot of worse things to become addicted to so why not set yourself up for future gains?
If anyone wants some info on the 60's shoot me an email and i will send you some. i am not a sponsor or a vendor i just happned to come across these and a few other things that should floor alot of people.

60 lb. per hour injectors in that set up , you would never get it to idle because you would have to turn the pulsewidth time on the injectors down to nearly nothing at all , so Shapiro , I would really like to see you try it . You really sometimes should listen and take advice instead of feeding advice to someonelse when you really do not know what you are talking about . No offense , I am not trying to be rude , but you probably just confused the hell out of this guy looking for advice . Even if you do plan on doing future modifications , you would probably have to spend around $10000 to have a set up to make enough power that it would be worth it to need an injector that big to adequately supply your fuel . Most people take it one step at a time and learn with each step (unless you are building a race-only car) , you go with the #30's , and a year or two down the road , when you are ready to upgrade (if you ever get that far) then you sell them for 10-15% less than you paid for them and spend that money plus a small amount more for the next required set .
Just my .02 .

mike72678, its your opinion and you know what they say about those, not to be rude 
. I have tried it and so have many many many others. If you read my Post you would see where i state they are easy to get to idle. Once again "I' have used them and "I" have had AWESOME results with them. If you haven't Used them don't tell me what they can or can NOT do because i have and i am Still using them. So Mike72678 you should practice what you preach "You really sometimes should listen and take advice instead of feeding advice to someonelse when you really do not know what you are talking about " and how can someone every take that as being rude 
I remember when they said Fuel Injection Sucked and Carbs could make more power any given day of the week, boy have Tech has advanced hasn't it. I guess you really can't teach some old Dogs new Tricks.

Damn ya'll made this thread complicated in regards to the injectors! The guy simply asked if 30 lb SVOs will support a cam only engine plus a 175 shot (I'll assume he means dry since the injectors would have nothing to do with it if it were wet.) As was stated, these will flow 36 lb/hr at the LS1's pressure. That will be good for about 575 RWHP. Let's say he's making 375 RWHP with a cam. Add about 160 RWHP to that and you get 535 RWHP. So, yes, they'll support it so long as you keep proper fuel pressure to them.

Shapiro , Well , I have done it with the low impedence #55's (switched the drivers) on a Mustang with a mild street build that had a 200 dry shot which is why he wanted it (not on my car , I used to own a shop) . We got the thing running great at full throttle especially with the nitrous on , but the damn thing ran like **** at idle . Th reason being is because the injectors were pintle style , and when you turn down the pulsewidth down too much they almost just dripped . We went to the #42's and everything worked out much better , the #42's can support around 600 hp no problem .
