Re: hello everyone :)
You would get better and more responses by posting in the appropriate category related to the particular system of the vehicle. These questions you ask here would be best in Engine section.
Also, if you're wanting to know static compression ratio, readers need to know piston used - flat top with valve reliefs, 2 or 4 each, dished piston, how much volume in dish, bore size, head gasket used, as in thickness, cylinder heads used, as in combustion chamber volume, stroke used and lastly, if known, how far the piston is sunk into the block, whether the block has been decked or not - can you read the engine code numbers on the front of the pass side deck. If you can, generally it is a sign the block has not been decked, piston would be 0.025" below the deck, original design.
Granted, alot of the info mentioned above may be a little deep, but generalizations can be given, industry standards, so to speak, to get a 'close' static compression ratio.
We would more than happy to answer your questions, but more info given, the better answer given in return.
