GM LS3 Piston displacement?

[nor_cal_cyclist]

In the process of working with a friend that has a Glowforge to make a new engine data plate for my resto-mod 1974 FJ40. The new engine is a 6.2L LS3, and while I can find most of the information/specs, the one thing I can find is the "piston displacement." Searching the web, and I found 1 reference to it stating "+3cc" - is this correct?

TIA!!
