New, never assembled 426 Hemi block casting number is 2468330-1
There are no stampings on this block.
This block can easily be bored to 4.250 (standard)
The sleeve has been removed from cylinder #7 and that cylinder is .030. I'll leave it to the buyer to decide if all the sleeves should be removed or if a sleeve should be reinstalled in #7.
The O-rings you see near the top of the cylinders are not due to the sleeves. Those O-rings were used by racers to help the head gasket seal under severe duty conditions. The O-rings can be removed by any competent machinist.
