I was reading in this small block ford book last night and i found where the writer said using a 351w block, 400m crank with the main journals ground to fit the 351w block, chrysler 360 rods with the big end machined to fit the 400m crank you'll get a 408w, i assume using 351w pistons since he didnt mention anything about em. Whuddya think? out local machine shop doesn't have the tools to machine a crank or i actually might consider it
