From Jim: " the stamped date on block indicates that on the 21st of this month this engine will be 100 yrs old, there is no plate or numbers to indicate serial or whatever, I have had this engine apart . the carb and distributor are not on engine as I took them off, both could be rebuilt, the dist only needs a set of cap clips and tlc, the carb needs a new bowl and lots of tlc, internally the bearings look quite good but one wrist pin needs to be freed up and the pinch bolt on that same connecting rod is stripped, all the valves are there but should be replaced and the seats need to be redone, the cylinders need to be machined but the rings are all free now . piston is 3 3/8" dia and stroke I take to be 5" "
