Ok, weighed them both. The 400 with the reid mopar bell, no converter 157 pounds
The 727 no converter 128 pounds.
The converters are too different to be a fair compare. Bolt together on the 400, and Coan billet front on the 727.
Add maybe 7-10 pounds for the big billet flexplate, and crank adapter on the 400.
That's another thing better with the chevy. The mopar stock style mounting of the converter using even the best small dia 4 pad flexplate isn't as good as a 6 pad style billet flexplate with the starter ring made into it.
Hmmm....interesting thaxs for the response.
