Safe Boring???

[Laramie4x4]

Hey guys.. i finallt got a core engine from work and it had a 2 spun rod bearings so the crank is trashed I have a replacement.. but 2 cylinders have a bit of scoring.. I was wondering how safe going over .020 to clean it up and to use the block for 1000hp application..its a CR block also.. I'm hoping I only have to go .010 but if I need more I want it to hold up...

No worries - you can go 1mm before sleeves are required... might want to go .020" over instead of .010" though, since that's a standard overbore. :Cheer:
