I've got a '72 I'm playing with and the non-dished pistons are about 0.110" down the hole. This calculates to 22.7cc. All the '72's I've looked at had no dish.

I just measured the CCs of my 72 360 with the pistons at TDC and grease in the ring grooves to seal them and no decking on the block and measureing the total volume in the cylinder I found 30 CCs in there
