One of the few things I saved all these years from my bus days is a rebuilt 1700 pancake motor that my plan is to build out to a 2 liter and put in my Vert someday. I scored a set of 94mm Kolbenschmidt pistons and jugs for $100 from a dusty corner of my local imports parts house probably 15 years ago now when they were getting rid of old inventory. (edited)
