Default Built z6 + Low compression > safe to run N/A?

So..I've been looking at a few online compression calculators.

And they all say the same thing, 7.5:1 (give or take)

Still really low, think it would be safe (drivable) enough to run N/A for a week or two?

I want to break it in before I bolt up the Turbo.

Setup is as follows (currently)
TT rods (roughly stock z6 length)
75.5 vitaras
OEM HG
Block isn't decked, head isn't shaved or polished or anything (as of yet)


Maybe I am just calculating it wrong?

Any help?

7.5:1 sounds correct for that setup. It won't hurt you to run it N/A, it's just going to be slow as ****.
