Ok, so its not a chevy, ford or mopar, but rather a BUICK! So the core I have is for a 455 Buick, but if anyone here is familiar with those blocks they know that at the bottom of the bore they are not solid, they continue down into a sort of lip or ridge. The blocks themselves are light enough to be comparable to a sbc, and thats the reason I took the block...power of a big block without the weight. The problem is that a rod broke and bashed the lip/ridge part of the bore on one of the cylinders. It broke part of the lip right out and its missing a good square inch of cast iron at the bottom of one of those cylinders. Is it repairable or is it possible to sleeve the cylinder and not have problems there? I mean, I don't think the block is good for high performance now....but is it useful or is it a really good boat anchor now?

Hopefully someone knows what I'm talking about.....
