Is there an easy way to determine compression ratio with the following information

[cactuss4]

and if not what am I missing?

416 LS3
4.065" bore
4.000" stroke
-4cc valve relief flat top mahle pistons
Cam 227/243 114LSA .614/.624 Lift


The Cam appears to be good to about 7K (a tad low) and good for midrange power with a Centrifugal blower (based on what comp cams say). Considering turbo charging, but the motor is built and running, so trying to determine the comp ratio to see if it's possible, without a tear out or should I just consider a blower and throw out my Turbo ideas?

Thanks
Tory

You will need cylinder head volume and piston pin to top of piston measurement to know the distance from the top of the piston to the top of the deck.

There are lots of online calculators you can use once you have that information.
