E7 Combustion Chamber Cc's

[f8tlfiveo]

Does anyone know what the stock combustion chamber on e7 heads is? I have a set of heads with 64 cc chambers.. Wanted to try to figure out what my compression ratio would be with these heads..or I guess if anyone has info on stock pistons that would prob help also.

All the searches I have done on here have come up with anywhere from 58-64...

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.

So I should be about stock ratio with the new heads then.

If they're 64cc...then yes, about the same.
