forged piston compression

[deauxt]

What compression ratio will a 17cc dished piston create on a stock bore/stroke 98 Cobra?

Going on Manley's numbers and a 52cc comustion chamber...this is about what I come up with:

flat top...10:2 to 1
11cc...9.2 to 1
18cc...8.5 to 1
23cc...8.15 to 1

Once again, thesae are numbers I have come up with for a 96-98 Cobra engine with the 52cc comustion chamber. Not perfect, but, probably pretty close. Once again, these are based of Manley's numbers
