    i have a LS block that is bored and honed .03 over. my question is what piston size and ring size should i use? (stock size piston w/over size rings?) i plan on using forged pistons so i can boost the motor a bit.

    thanks for any info

    You're a bit too big for 81.5mm pistons... so you'll probably have to go to 82mm and have a machine shop match the block to the pistons. That's the right way to install aftermarket pistons anyway- match the block to the piston size, not the other way around.
