Nitrous question for curiosity sakes

Had a discussion with a buddy of mine who races sb mopars has a duster with a sweet 360 pushing 2 stage 250 shot of nos. an 8.5- 9 second car. I have nothing that fancy.

I have a 74 duster with a ford 9" and 3.89 gears. I am running a magnafuel QuickStar 300 fuel pump and regulator. My engine is 383 with stock bottom half 915 heads with the intake valves of 2.08 and exhaust of 1.74 no work done. I have a purple shaft cam with 248 duration and 509 lift. I have a team g intake with with a speed demon 850cfm carb. The top half was just rebuilt and being put back in next weekend. Just have to make the descision on what headers from tti to buy.

Now with that info here is my question. Can I run a NOS sniper system with a 100 to 125 shot of nos without damaging the pistons. My compression ratio is measured at 8.8:1. Buddy seems to think there will be no problem with it. Since the engine does not run lean and cr is right on. What do you think. I have a sniper system minus the bottle. It's a bit old but considering it once I tune the Engine back where it was running before. It averaged 12.5's but would like to see faster. Next build will be a 512 stroker but can't afford it right now
