I'm sure this has been talked about many times on here and apologies for once again starting a thread on it. But I can't find the answer I need. I just want to be damn sure. Stock bore on 4g63 is 85mm so .020 over is 85.5mm correct? My search continues.

I am taking the same route I am building a stroker out of a block that is already bored .020 over so I just need the confirmation. Thanks.

before you order new pistons have the bores checked. then order pistons.
