For sale is a 870 casting number 327 block that is standard bore and has been baked, shot peened and magged and will clean at .030. This is a no suffix code over the counter block that has never been decked so it can be suffixed to your restoration as needed and be correct. Also included is the matching standard steel crank that will clean at -.010, and rods (not pictured) Super nice pieces that would be a steal for a numbers Corvette restoration. I will crate and ship. I have lots of early SBC OE perf parts so let me know what you are looking for. Thanks for looking.
