LA Sleeve Co charged me about 550 to have a new sleeve put in. Does not include pistons. Now this is for a single sleeve of the OEM type. They do offer the Darton sleeves and other similar sleeves. I chose to go this route because I have block guards installed in my engine and the cost to replace the block would be almost 1k.
If you have this done, just take a piston with you and they will bore tot he correct size to match the other cylinders.
