I have all of the numbers needed except for the cylinder head chamber volume. A quick search online came up with 52cc’s. The valves were the same for all the Healey 3000 engines so the head volume should be the same. Would anyone be able to confirm if 52cc’s is a good number?</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Harold<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
