...not that I would really need to know, because I trust my busy engine builder - but it would be nice to know the specs of these Manley LS7 pistons. I'm guessing there's something like -18cc dish, as with 74 cc heads, compression ratio is around 9.8:1. But is it so?

I tried to google, but no luck. :-(

The number on the bottom of that piston is just the casting number for the piston blank. It will not give you any info about the CC of the pistons. If they came from us at SDPC and it is a dish pistons, it is a -14cc dish.
