I have for sale a nice set of low compression blue top pistons and rods. Pistons are equipped with 18 mm. pins; rods have 42mm bearings. Amazingly very very minimal wear on the skirts. Piston #4 has a ding on the piston crown near the upper ring land (I deburred the edge). I went ahead and soaked the pistons in cleaning solution and wire brushed the carbon off the rings. Pistons came off a low mileage late model bluetop.
