Need help figuring out my dynamic compression.

Static compression ratio of 11.73:1.
Effective stroke is 2.98 inches.
Your dynamic compression ratio is 8.99:1 .
Your dynamic cranking pressure is 185.88 PSI.
Your effective boost compression ratio, reflecting static c.r., cam timing, altitude, and boost of 0 PSI is 8.99 :1.
V/P (Volume to Pressure Index) is 176

I'm guessing a hair on the cam specs. The DCR calculator wants at seat specs. Which for some reason hughes never gives, your cam lists them in .050. But I have a handy little formula to fix that. I used a seat intake valve closing of 70, you can probably phone them to get an exact number. You should be around 9:1 dynamic compression.

If the heads are aluminum. You're fine on pump 91. Generally aluminum heads have a max SAFE limit around 9-9.5:1 dynamic. If you're on iron. You might want to run maybe 94 or something instead. Generally SAFE DCR on those is 8-8.5:1. Now. That's SAFE limit. You can definitely do more. There's lots of guys running 200+ psi on pump gas. But your tune needs to be exact. Timing is critical. And even a small hiccup can cause detonation. Something as small as wrong plugs can throw a wrench in it. So it take's a lot more babysitting. Of course closed chamber. Better flow. Valves. Etc all play a part in reducing detonation.
