200-4R Behind a 340 and Reid Bellhousing Build

I wonder how much difference there is fluid weight?? I imagine the larger convertor can hold more fluid but not sure about the transmissions?? Fourth gear has to add some weight as well. Trans fluid probably weighs 6 -6 1/2 lbs per Gal??

Hmm I’m unsure. The 727 held about 8 or 9 quarts and I don’t know what the capacity is on the 200. Both transmissions were drained and had fluid in both converters.
