Default 30 over 5.3 pistons
I am having trouble finding forged pistons for a 5.3 bored .030 over, does anybody know where I might could find some? I am only looking for name brand parts only Thanks.

If I'm not mistaken, you should be able to use some forged LS1 pistons.
LS1 bore size is 3.893
LM7 bore size is 3.779

So Just find the right oversized ls1 Pistons
