Now it's been about 18 years since I've had a set of these to play with, but if memory serves correctly, it is in the ~160cc range. Good for low-end torque, not good for high-RPM performance. It is possible to work a set of these to get another 8-10 cc's, but that's still not good for high-RPM (but it's better than stock).
They do make good low-end to midrange torque, and are well suited for a large car such as a Caprice or Impala. Just make sure you're using flat top pistons so that the 76cc volume doesn't lower the CR too much. They were stock on 350s and 400s from about '71 or '72 through '77. The '72 Impala I had eons ago had these heads stock, as did my '75 Caprice Classic.
