200-4R Behind a 340 and Reid Bellhousing Build

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.
