The Block is a 230 cid. The crank came out of a 250 cid. Pistons where Standard out of the 230 cid block. The 250 cid block has a taper of .0005 out of round .0005 Bore 3.8780.
The Crank,Cam,Piston Rods im using in this 230 block. All came from the 250 cid block.
Why replace Blocks? On the Carb side of 250 cid block is a foot long crack in the water jacket. Soo I need a new block. Best block I found or got my hands on is this Chevy 230 cid Inline 6 block. Hope this explains it all.
