Here is a used set of 8 CP Sb Chevy Dome pistons with aftermarket rods. The pistons are 4.030 bore, 1.250 compression height and use the .927 wrist pin. The rods are 6" long and 2.100 crank pin. 1 rod is bad as seen in pictures and 1 piston has some scuffing on the skirt i believe it is still very usable. We do combine shipping on multiple items.
