LS3 block questions

I destroyed the block in my Z06. Im pretty broke, so I am trying to redo it on the cheap, and keep it reliable.

Can a LS3 block be safely bored to 4.125? Are the sleeves long enough for a 4 inch stroke?

Thanks
Tony

No, and yes. 4.100 can be done on some of the blocks depending on how straight the factory put the sleeves in.

Do a 4.080 x 4.00 and get yourself a 418 I have and am very impressed.

cheers

6.2 block, sleeve alignment can be an issue on them, i'd stick to 4.080, anything over that for clean up only.
