I have listed a link to calculate compression ratio. I know a few people have asked about this and I was also curious.
Hope this provides some useful information for members.
http://www.csgnetwork.com/compcalc.html
The only info lacking is the bore diameter of the gaskets.
Springer referenced 3.85 bore for a stock 88" gasket and .052" thickness which probably crushes to .045"
Cometic Gaskets are the thickness specified, they specify the crush thickness.
If sombody could provide the bore diameter for a 95" gasket it would be helpful.
Thanks
FYI other numbers
88" 95"
Bore 3.75" 3.875"
Stroke 4.0" 4.0"
Head CC 85 85
