Identifying pistons, any help?

Hi guys -

I'm picking up an LT1 short-block this weekend but need help identifying which pistons it has (they are SRP forged, but I need to find out the dish volume). Any help or suggestions?

Thanks.

You can start by looking for any markings or numbers.

I figured that, but I'm driving up to pick it up and if I can identify what's in it before I drive off with it, that would be best. Do manufacturers put the ID on the top of the piston? It's all assembled.

If you look in from underneath, I think SRP always labels the underside of the piston.

For example, in this picture, "40D" indicates a 40cc dish.



I'm not 100% sure of that, though, so you should probably call SRP.
