How much can a 200 block safely be bored? I got mine back from the machine shop, and now theres a big groove in the #1 cylinder :devilish:

And thats AFTER i had them bore it! So im going somewhere else, but im not sure how much it can take, since there kind of thin walled.
 
Mine is bored .60 over without any issues. Personally I wouldn't go any higher. I've heard of .80 over kits for sale, but I think you would have some cooling issues.
 
Mine's also bored .060 over with no problems. Ford says you can safely bore them out to .080 according to my Ford motor manuels.

Later,

Doug
