Hey dudes, quick question here. Is it possible to overbore the block sleeves in an F22 engine (much in the same way a small block Chevy would be punched 30 over, 40 over, etc) or do you have to flat out replace them once they go out of spec?

My uncle told me yesterday the sleeves absolutely cannot be punched, but he's been wrong before (he tried to convince me the 700R4 was not possible to get in third generation Trans Ams, LOL).

 

Yes you can. But going more than 1mm over isn't ideal, and 2mm is basically the absolute max.
