Hardly seems like worth the trouble for 60 hp, but I can see why with marginal trans...
I knew a fella longtimeago who ran in the 1940's..."Mother Sill's remedy" we were chatting flathead fords by a creek, 1973. He mentioned that there were a few very late production 110 hp. I beleive most were 90, and the little bitty early 60 hp ones, which I remember seeing in wrecking yards... Pity I didn't have a place to keep all the cool stuff that's went to the blastfurnaces of China and Korea... Mine was probably 90. Gave 35 dollars for the motor, 50 for the car. 3 on tree with OD. Life on another planet....
