No, there are machine shops around here that will perform sleeving the block.They all start around $1200.00 and up.Could you sleeve that block on a Bridgeport mill? Like I had said earlier I can still find a 235 for around $600.00 bucks. I was just shooting in the dark earlier when I'd asked about .100" pistons. I just figured if anybody would know it would be that dude back in Tennessee, just kidding, like I said thanks for all the help.
