Yep, its fairly easy to do, as long as you have the proper measurements
for your engine. I put a compression ratio worksheet together to include
with an inexpensive cylinder head cc kit that I sell, but I also have the
worksheet on-line which you are welcome to take a look at. If you go to
http://www.steigerperformance.com, click on "Product Documentation", and
right up near the top of that page you'll see a couple of links for
"Compression Ratio Worksheet"; one of them is in PDF format if you prefer
to work it out yourself with a calculator, or the other is in Microsoft Excel
format, you just plug in the numbers and it'll give you your compression
ratios.
Or, if you don't have excel, a google search will no doubt
turn up a bunch of them, of varying degrees of accuracy and ease
of use. :-)
