I have an engine block that was upgraded when a new engine was built. This one is a 1977 casting, 4 bolt block that was detailed at Gale Banks about the time I worked there. It was cut for O-ring wire which has since been replaced with copper wire and surfaced to run with modern MLS or other head gaskets. The intake valley was completely detailed for better oil return. Current bore size is 4.280" (.030" over stock 454). I believe it will clean at .035" over if you wanted to have pistons made, or certainly it could be bored to .060" over (4.310). No visible damage, the engine did not ever fail. Do note there are some helicoils in the head surface of the block. $500 to be picked up in Parker, AZ.
I do have a couple of other blocks I may let go, including a standard bore GM tall deck block that has one sleeve installed by Gritch prior to his passing.
