Need help figuring out my dynamic compression.

Here's what I came up with using the Wallace Calculator

Camshaft, Rod Length, Boost and Altitude Correction to Compression
Static compression ratio of 11.65:1.
Effective stroke is 3.39 inches.
Your dynamic compression ratio is 10.03:1 .
Your dynamic cranking pressure is 213.79 PSI.

You'll need to mix race fuel IMO. 8.0 for iron and 8.5:1 for aluminum heads is the rule of thumb for pump gas. Not the rule but a good guideline and you're way above that.
