Calculating Compression Ratio
If you've always wondered how to measure an engine's compression ratio, this is a very informative video. You'll need a burette (which you can obtain from a laboratory supply company).
Remember that bore and stroke will be different for each car (the video is for an MG-A), along with the volume of the head gasket, so adjust your calculations accordingly. (Quite a bit of math in there, but a great video.)
