ITS GOT TO BE COMPLETELY STRIPPED DOWN AND GO TO THE MACHINE SHOP TO BE CLEANNED AND MEASURED TO SEE WHAT YOU,VE GOT TO WORK WITH. I WENT THRU 3 - 292 BLOCKS AND NONE OF THEM HAD EVER BEEN APART TO GET 1 USEABLE BLOCK AND EVEN THEN I HAD TO GO .060 OVER AND SLEEVE 1 HOLE. THESE CHEVY 6'S ARE BAD TO WEAR OUT THE FRONT 2 CYLINDERS BECAUSE THOSE RUN SO MUCH HOTTER THAN THE REST HENCE THEY WEAR THE MOST. JUST TRYIN TO LOOK OUT FOR YOUR WALLET.....
