We got in a great running 427 Chevrolet Big Block Engine the customer wanted to Rebuild. We have his Great shape used Factory OEM 1966 to 1969 ( Casting Part Number 3925579LH ) Piston set to sell as all 8 together.They all measure properly for the Standard bore size of 4.250". All the skirts are in very good shape (Pictures showing all skirts) 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). I wire wheel cleaned the top of just the one piston. We will leave it  up to the new owners to decide how they want to clean them. Please make sure these are correct for you, we do accept returns, but buyer would be responsible for shipping and inspection.
