    Default Speed Pro piston specs?

    I bought a set of speed pro powerforged pistons on Ebay. I was asked by my engine builder for the specs on the pistons. Does anyone have a spec sheet or card that comes in the box with the pistons or is the info on the side of the box all he should need? The part # is L2256F30, Thanks in advance.
