Latest shop project- - - - -I'm in the process of building an indexing fixture to assist in setting up stovebolt crankshafts for stroke changing. The standard stroke for a 235 engine is 3 15/16". By offset grinding the connecting rod journals and using a different connecting rod, rod bearing, and piston, it's possible to get strokes of 4", 4 1/8", and even 4 1/4", I believe. Ditto for GMC crankshafts. The crankshaft is set up off center in a lathe with the rod journal as the center point, and the new stroke is roughed out by machining the rod journals, then it's finish-ground to size in a crankshaft grinding machine. Old school technology- - - -my father was doing the same thing on flathead Ford engines in the late 1940s, but stroke changing has become sort of a lost art!
