Stock -70 340 block with nitrous??

Hi,
I have fresh built 416 small block. Block is stock 340 from 1970. Sonic tested and all necessary mods are done. Crank is Eagle forget, rods are Eagle H-profile. Pistons Icon forget flat top pistons.

Heads are Edel RPM full ported with 2.055 valves. Flow numbers are .6" lift at 303.9 cfm@28" H2O. Intake is Victor, ported as well. Compression about 11:1

Camshaft is Hughes STL6064AS, Lobe 108, lift .615/.621", duration .050" 260/264

Carb is Quickflow Q850-AN.

So, i have small nitrous kit on my garage. It is 100hp kit. I know that stock block is not immortal. So my poll is; install nitrous or not... If is obvious that block cannot handle more power than i forgot whole idea. But if chance is more that 65% that this block can survive, then i'm ready to take a risk...
