How much Compression can I run LT1?

I want to go the maximum amount on compression. Can I run 12:5 on a LT1 with 93 octane?

Dynamic compression is really what determines the answer you are after.

Summary. DCR is the compresion durning fuel ignition after pressure has been bled off the cylinder by the cam. I think that is generic enough yet still get the point across?
