    relax,

    Have a brew.
    81mm stock bore, BORGOS

    Newbore 3.228 in
    stroke 2.845 or 2.890
    combustion chamber vol. 37cc
    head gasket thickness 0.061
    head gasket bore 3.296
    piston to deck clearance 0.054
    dome volume/ dome relief 5.8cc (number given by JE Pistons)

    Using above said calculator gives me a capacity of 3.052 litres and a comp ratio of 9.1229:1
    if the stroke is 2.89 comp is 9.25:1 capicty 3.1L
    if head cc is 35 and stroke 2.845 comp is 9.484 cap 3.05L
    if head cc is 35 and stroke 2.89 comp is 9.61 cap 3.1L

    Rizzo--if you have a 2v 308 you can just order standard Daytona pistons i think and get a compression bump---if you have a 4v motor the piston is very different....
