Don't know if this is any help or not, but on my webshots pages, under the 224 to 235 engine swap album, photo 7_22_3 is a photo of the front of my original 1940 motor with the water pump. This is a 224 motor, the Canadian cousin of the 216. The only difference is it uses aluminum pistons instead of cast iron and they are a tad larger in diameter.
