RE: Check the back of the block. |

Peter, The ONLY way to find out if its safe to bore over the .030 is a Sonic Check, I have sonic checked over a hundred 428 blocks and have found great core shift on most. Many at .030 will have under .075 thou thickness, if its not on the thrust side its not so bad. I like to see .100 minimum after boring or slightly more. Someone suggested offset boring this may help the cylinderwall but can cause other problems. An easy way to check for core shift is to look at the lifter bore's as the material around them should be even if it is offset there it for sure will have cylinders the same way. The sonic test should only cost about 40-50$ american to have this done in the states, not sure in your area. Be very careful of having all 8 holes sleeved. It can be done but MUST be done by someone who has had great success in the past as probably 90% or more here that have it done have at least a couple cylinders leak afterwards. Hugo |
