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...
