E7 Combustion Chamber Cc's

Low to mid-60's is the general consensus. They vary based on casting, the amount of casting flash, etc, but that's the norm. I've never seen an E7TE head in the 58-60cc range. At leat not without some milling. Compression will be around the 9.0:1 range. A cubic centimeter here or there isn't going to make a lot of difference.
