Default Piston movement...

I bought a core engine and am getting it ready to send to the machinist...

Happened to notice that there is quite a bit of side-to-side movement in the pistons..

I'm able to get an .030 feeler gauge in the gap no problem..

I don't have any way to measure the bore except at the top rim..it's about 3.909 to 3.914..

I'm thinking those .030 over pistons have been in there a very long time...there are piston expanders in the skirts...
