My dynamic numbers:
Static compression ratio of 9:1.
Effective stroke is 3.60 inches.
Your dynamic compression ratio is 8.05:1 .
Your dynamic cranking pressure is 160.26 PSI.
Your dynamic boost compression ratio, reflecting static c.r., cam timing, altitude, and boost of 20 PSI is 19.00 :1.
V/P (Volume to Pressure Index) is 185
There's another handy calculator that you can download at the bottom of this page: http://www.empirenet.com/pkelley2/DynamicCR.html
You can use this one just to calculate your intake valve closing timing that you need for the other simpler calculator (if you already know your static CR).

Might as well keep it moving...
Compression Ratio: 9.5
Motor/Displacement: 325
Amount of Boost: 9psi
Type of FI: TVS1900 & S475 sequential boost
Meth Yes or No: Not yet..
Max Power: ~520
Verdict: It's quick, but this setup is in the very bottom of its efficiency range. Need a bigger engine to really pick up some power. Will be swapping to a 408 eventually. The 5.3 will get a meth kit and a retune here in the near future which should put it closer to the 600rwhp range.

Compression Ratio: 9.5
Motor/Displacement: Forged 370
Amount of Boost: 8-14 depending on how I feel
Type of FI: Trick hot parts with t76
Meth Yes or No: Yes single nozzle
Max Power: 630rwhp/690rwtq old number with stock motor. Don't know with the new motor yet.
Verdict: Feels a little weak out of boost with a 2k stall and 80e but pulls hard on the top end.
