<VV> CCing Heads

[Craig Nicol]

Bill asked:
Anyone have some volumes in cc for heads on a 164CI engine bored .030 over.
Looking for compression in 9:1 to 9.5:1. Thanks, Bill Loftin

Craig Replies: 49-50cc

Chamber volume (cc) + head gskt + deck height + cylinder area

Divided by

Chamber volume (cc) + head gskt + deck height

Equals compression ratio

Example: 49cc & and zero deck height:

BDC= 49cc + 5cc + Occ + 454cc = 508

TDC= 49 + 5 + 0 = 54

508/54= 9.4:1


50cc = 9.25
