any know the weight difference between L92 and LS3 pistons?

 

reason I ask is the crank I have for my LS3 build is out of a L92 and just wondered if it needed to be rebalanced, doesnt look like it needs to be, the Part# for the L92 crank shows to fit the followings:

The L92 piston has a thicker crown to make up for the exhaust valve reliefs so it is same weight as LS3.

 

Probably wouldn't make that much difference honestly. Factory stuff isn't balanced THAT well

 

L92 pistons have two -2cc intake valve reliefs per piston. Can't imagine that making a big difference.
