well im looking more for the jsut the combustion chamber volume, you know like when you are looking at ordering v-8 heads they usually give how many cc's they are. heres a link to summit showing the specs of a certain head and it shows combustion chamber volume (59) and thats the number i need for the Ecotec. http://store.summitracing.com/default.asp?Ntt=heads&x=0&y=0&searchinresults=false&Ntk=KeywordSearch&DDS=1&N=115&target=egnsearch.asp

sorry im not the best at explaining things haha thanks for the try hope that clears things up

lol i knew what you were talking about Roy, and i even took the time to search for you, but I also found nothing..sorry

do you still have your old motor and head? i'd say go "CC" that if you still have it..

yes i still have the stock head and block

bring it somewhere to get it done, or i'm sure you can find a way to do it yourself (liquid and and graduated cylinder)

or if i remember correctly NJHK did it awhile back, ask him

AFAIK, Adam, just bought a Patriot performance ported head... i don't remember him ever menitoning getting it cc'ed unless Patriot sent a spec sheet along with it.

Stock Ecotec head combustion chamber volume is 53cc's. It is a stock head so there will probably be variations, and it never hurts to match the chambers when you get the head ported. Any good port job will include a chamber cc. If they don't offer it, don't buy their stuff.
