New pistons ??
Just wondering where to buy some pistons for my motor,
took the pan off to inspect the bearings and noticed that they wore pretty bad, after measurement,
so im doing a rebuild
any help would be great thanks

Series 1 L27 piston is 12537200. Supercharged Series 1 piston is 24502091.
GMPD:
This is true for 91-93 L67. 94/95 uses 24503974.
I'm assuming the change is to have the coating extend down the skirt like the S2 L67 pistons do. But this is just an assumption.
GMPD:
GM PART # 24502091
CATEGORY: Engine Piston
PACK QTY: 1
CORE CHARGE: $0.00
GM LIST: $132.75
OUR PRICE: $78.70

Another option you might consider is hypereutectic pistons. They're quite a bit lighter, but are also quite a bit more expensive. I would suggest only using these pistons with lighter rods, H-type erhaps.
Use these if you're going for power. If you're just doing a rebuild for a daily driver, stick with OEM.

The least expensive pistons are Sealed Power (Dana) replacement pistons, available in overbores, and they are coated like the GM stock pistons.
