454 SHP 4 bolt main std bore

[F41427]

1978 date 454 with the large oil boss above the filter. The block was just cleaned magged no cracks then shop peened. The caps were bead blasted. Notice The casting numbers were stamped backwards from the factory. Comes with choice of GM Dimple rods pressed or floaters.
The Machine shop said the bores will clean up at .020. That is all the work I had done. Same foundation as the LS6 blocks just different casting number and date. No vin stamp present. I do have the windage tray bolts just not pictured. This is a super clean solid block to have built and hard to get std bore still. $2,500

Do the cylinders have to be machined?
