This listing Is For A. GM, LT4 / LT1 Series 6.2L STD Cylinder Bore Bare Block.
BLOCKS ARE NOT TAPPED, DRILLED, FOR AIR PUMP. YOU CAN USE THESE FOR THE L86 ENGINE, BUT NO AIR PUMP. IF YOU ARE IN NEED OF A NON D. Block's Have About 10,000 To 65,000 Miles On Them. Cylinder Bore's Are In Nice Shape, Some Might Have A Light Mark, Scratch Here And There If Any (NOTHING YOU CAN FEEL WITH YOUR NAIL), (Very Light Small Spot Of Surface Rust) But Nothing That Would Not Clean Up WITH A HONE ON A DRILL. Smooth Main Cap Bearing Surface. All Ways Good While It Is Apart. You Can See From The Pic's Still In Great Shape.
