Actually the oxide is the important part of N2O. Nitrogen is an inert gas, it is the extra oxygen molecule that separates under heat and pressure that is important.

Probably the bigger issue is will the block take the extra heat generated and what are the resulting oil temperatures going to be.

Actually, it drops intake charge temperature, and the only very noticeable effect is increased cylinder pressures (which is the thing you need to worry about). Particularly, using such a big shot to just blow a rod through the block. Burning a piston/piston ring can happen too of course. Either way, the key is to make sure you're spraying enough fuel to compensate, and to not use such a big shot that your bottom end wrecks itself.

Yes intake temperate does drop (because it's an expanding gas) but burn temperature is higher due to the highly oxygenated atmosphere and additional fuel burn.

It's usually not a problem as you're only doing this for a few seconds at a time typically.
