I've got one of those 90.5 MM diesel pistons on order. I'll have a test block mocked up soon to do some actual measuring on- - - -not a WAG from a parts catalog. Of course, I've got the equipment on hand to actually produce some of these exotic parts- - - - -lathe, mill, boring bar, Sunnen hone, line bore machine, etc.- - - - -all I need is enough time to use them!
