Does anyone know the hole size in the 1936 Super 8 water jacket distrubution plate? The brass plate that I have has 1 inch holes. I have seen other plates that have 1/2 inch holes. I have found speculation that the holes are larger at the rear of the engine. It looks like an easy job to make the internal plate if I knew the hole size. Thanks for your help.

I assume in order to get more-or-less uniform flow volumes across the length, the hole diameter varies front to rear in the Eight plates, it doesn't make any sense to me that the Super 8 plates would be different.

I'm not sure they are. Does anyone have an old 1936 water jacket distribution plate they could measure the hole size. Thanks

Does anyone know if the holes in a 1936 plate is the same as a 1929? The 1929 plate I have access to is 1/2 inch holes. Thanks

Lots of differences in the design of the plates over the years, I don't know if this is helpful to you or not. Sorry I can't credit the photo, forgot where I got it from.
