200-4R Behind a 340 and Reid Bellhousing Build

I have heard about less frictional losses in these transmissions but I wasn’t going to make claims that I couldn’t prove some data with. Is there anything out there that you know of that proves this?



No floor cutting with this swap either.
I thought the us cartool mount required cutting th floor. Not having to is good news. We’re you able to keep your torsion bars too?
