Cam Timing vs. Compression

formulas.xls is a spreadsheet based on Jeffrey Diamond's technical discussion of Cam Timing vs. Compression at http://victorylibrary.com/mopar/cam-tech-c.htm I hope to eventually turn this into a JavaScript form that you can use online. It's fairly self-explanatory with pop-up notes that explain each of the equations. To use the spreadsheet, you will need to know either the Chamber Volume of your engine or the Nominal Compression Ratio.
