Hello all,

I am new to this forum and I haven't been able to find a clear answer with my searches, so I hope someone can help. I have been putting together a 292 y block that I purchased "rebuilt" a few months ago. The engine has already been bored .060 over, but it has some rust build up in two of the cylinders where water had sat. I have already taken it to a machine shop to have main studs installed and for line honing. They told me that they ran a quick hone into the cylinders to clean up the rust, but it didn't seem to help. I don't want this engine to burn oil, so I think I'm going to have to bore it further. I haven't been able to find 292 pistons that are larger than .060 oversize, but I've read the block can be bored up to .120 over. Is this correct? I've read that I could use a 312 piston, but would I need to change the rods or crankshaft? Any advice or information would be greatly appreciated.

Thanks,
David
