SPEED PRO Hypereutectic H727CP40 Pistons Set of 8 for BBC Chevy 454 .These Big Block Chevrolet Pistons are in great shape. The owner only had a 1000 miles on them and wanted higher compression ratio for Racing, so here they are for sale. They all measure properly for the final bore size of 4.290" That is 0.040 oversize. All the skirts are great and pins float properly (we are showing close pictures of all the skirts). We used an OTC Fixture (That supports the rod only, and no stress to the piston at all) when pressing these off the rods.( picture shows that OTC Fixture). Call (952)854-5 seven eight six
