I would surely think so. as long as you change the oil regualarly. I'd step the plugs closer. i have freinds that spray ls1's with 175,000 miles on them.i'd say a 100 or 150 would be safe with the right plugs. Not sure which plugs the lt1 guys use for n2o though.
You need to buy a 1step colder heat range copper ground strap sparkplug.
NGK is the most popular brand for spray. The Parts house can tell you the
plug number. Also buy a sparkplug gapping tool. It's cheap to buy and pretty easy to use. You bend the ground strap on the plug GENTLY or tap it down GENTLY to close the gap to in your case i'd suggest .044 as a starting point.

looking for more power !
Make sure your fuel pump is up to task (like stated above), fuel filter, colder plugs, and maybe even a new set of injectors (or have the stock ones cleaned). These would be very good precautionary measures. If you can do the work yourself it should cost you about 300 bucks total ( if you just have the injectors cleaned, and dont buy a new pair). I suggest the injectors because i figure which such a small shot you will be going with a dry shot(safer) but if you go wet you should be fine w/o them.
you can be safe and run a 150 shot all day long. ChiTown racing by me was tryin to blow there lt1 up on purpose and ran a 400 shot all last year and never blew the motor!! A few of my buddys are runnin 150's all day long with no problems. So a 50 shot you say..... i would spray a 50 shot from every light i left!! But thats just meeeeeeeeee, haha
I dont have NOZ yet but i've been doing alot of research on it. From what I read U can use a little over a 100 shot and still be safe on a stock engine as long as u get all the proper stuff on a kit. U should read the "sticky" it well tell u every thing u need 2 know about noz it helped me out a hole lot
