Pulled the 727 out today and weighed the units. Here’s the scoop:
727 with 8” converter 153 lbs
200-4R with 9.5” lockup converter 177 lbs
The converters weigh 10 lbs different. 33 lbs for the 9.5” lockup and 23 lbs on the 8”. Sucks having the extra rotating mass but it was expected. Should slow the car a tenth or so.
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 to 6 1/2 lbs per Gal??
