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.

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.

Anyone want to make a graph with all the numbers of the info given!!

CR = x-axis
Boost = y-axis
CID = different colored dots.

Not sure what exactly you want to see, but this is displacement graphed against boost and CR,

I think having the CID the way you have it skews the graph a bit. I think if one color could be used for the 290-350 CID engines, one for the 350-400 CID engines and a third for the 400+ CID engines would make things a bit clearer.
