I just CCed one of my heads. I got 62cc in both chambers. I thought that stock was 60cc? Does this mean that the buret that I bought is a POS?
By my math, 62cc chambers would give me 9.2:1 with a .040 deck height on a 96x78 mm 2258cc engine... 60cc would give me 9.4:1. Heads need a rebuild... I'm just trying to figure out where I'm at for a starting point. |

The largest O.E. chamber I can recall measuring came in around 61cc's. Most unatlered OE chambers come in around 58cc's.
Todd if you are getting consistent repeatability, then your method is probably good. I use wintergreen rubbing alcohol. Cheap and cleans up easy. Make sure that you purge the valve of air before measuring. These chambers were sent from the factory in as cast condition, and they do vary. A 62cc chamber is not tough for me to believe. |

Thanks Len. I'll measure one more time to verify... You'll probably be seeing these heads sooner or later (IMG:style_emoticons/default/biggrin.gif) |
