    Over bore ?

    Anybody have experience with a 0.02 over bore ? What pistons did you get ? What pistons size would I need. First time with an engine that needs to be bored out .so I'm a newbie lol.sorry I know this is stupid to ask such a broad question

    Best to have the block bored and honed to the pistons. So if the bore cleans up with a .020 over bore order your pistons and have them hone the block to final size. Different piston manufacturers will have different piston to block tolerance. Chose a piston that meets your needs -goals. No advantage have forged pistons for a stock rebuild
