I have an extra 427 Center oiler block. Excellent shape, no sleeves, no cracks, etc. Was run for a short time at 20 over. I figured I would bore it to 30 so I could use standard pistons. My machinist said it could be honed to around 25 over and special order pistons could be used.....your choice. I have an enclosed crate to ship this by....must go truck line (around $100 shipping). I paid $3000 for this last year since it was in such good shape. Email me at
