Compression Question?

I have pistons that have 11.2.1 Compression with 60cc chamber heads. My block is also decked 0.020 over factory.

It is a 92 5.0L block just in case anyone has a compression ratio calculator. What is my compression ratio?

I worked out a CR calculator in Excel a while back.
You can find it here...

It will take into account more factors than you have provided, so you may need to get some more info.
It should be pretty accurate.
You will have to have Excel to open and use it though.

If you try it, let me know how it works for you.
I can always refine it, for ease of use.
