Hey guys, I have a 5.3 cast iron block that has a hole the size of the tip of my pinkie finger. You are looking at the #7 cylinder, motor is upside down on the stand. Not sure if that is the water jacket or not. On both ends of the block there is a cap to this channel. Can this be fixed?? If so, can it be fixed correctly that I wouldn't have to worry about it. I would obviously like to salvage the block if possible. Please give me some insight and opinions. Thanks.

I know you guys said to scrap the block but.... I have a very close family friend that owns a machine shop and has been building race winning engines for many many years that said he wants to look at it first. I showed him the picture I have posted and he said that thinks he can fix it without to much issue. This guy has forgotten more than most of us will ever learn so I am going to trust his opinion when he looks at it in person. I will fill you in on what he says.

yes, the #8 rod broke and caught the block. You are right......no sense in taking a chance on it. My problem is finding just a block. I called several places today and nobody has just a block. I talked to Tick Performance and they have an LS1 block for $250 but he told me he doesn't know if the cylinders can be cleaned up so I surely don't want to spend that kind of money on something that I don't even know can be cleaned up. If anyone on here is in the NC/SC area and have a block let me know and I will contact you.

You are 100% correct.....he can do both. I am still going to get another block regardless. Do you guys think I should go with a cast iron 5.3 block bored to 5.7 or just go with a LS1 block to start with. My ride is a 02 Tahoe 2wd.....
