It doesn't have everything, but I'm keeping the app in hopes of updates because it's better than anything else. Could use things like piston compression height and quench height so engine could be clearanced/blueprinted.

It would have been better if the numbers were not automatically rounded off. But other than that it's a great app and a useful one too

I put in all the values of a stock gm engine and found that there was only buttons that changed what I had put in. Shouldn't there be a button that totals it all up and tells you what you get or that what you put in won't work out? Or even a wiki or something to explain how to use it for those of us that aren't as familiar with this stuff.

This shows my compression ratio would be at 9.5. After using the actual formula, I would really be a 8.67. Needs work, but a good start.
