| RE: 428 pistons |

Guess what..I'm going through the same thing. I have a std bore 428cj that had a little surface rust. It was measured at about the same wear but once it was bead blasted and magnafluxed it was found to have .010 wear at the top of the cylinders. I was told to take it to .020 over. You can get .020 over from KB Silvolite part # 1138. It is a replacement typre piston..so it is cast. If you want forged you will need to get .030 over or custom. Unless you plan on using forced induction or run high hp, the cast will be fine...afterall that is what survived in the blocks for all those years. I am just going to take mine .020 over along with line honing, balancing, etc.
If it ever needs a rebuild I will just have to take it to .030 over. If you think about it, custom .010 over aren't worth the high $$ over a .020 over cast piston unless it will be raced. If you have any other questions just email me. |
