What's the cold cranking dynamic CR on a stock 180?

If you know the cam specs, try plugging those into this:[www.wallaceracing.com]

I did this at one point on an early turbo and came up with 7.5:1 or less.
my cold cranking compression is usually around 125 psi with 8.0:1 static compression ratio.

I played around with the calculator and plugged in various cam closing angles until I got my measured cold cranking pressure and came up with 6.68:1 dynamic
