Selling the SB 727 out of my Dart. It was in the car when I bought it and supposedly rebuilt prior to me buying the car. Valve body is a Cheetah 17680. I had a custom 8” converter built by Dynamic Converters that is stalled at 5500 rpm. I have put about 1200 miles on the car since I’ve owned it so there’s not many miles on the converter. Never had any temp issues. 190 degrees was the highest oil temp I saw even on 100 degree days in stop and go traffic and highway driving. When I took it to the track last fall, it went 10.40’s @ 128 mph with a 1.48 60’ and didn’t feel any problems with the transmission or converter. As far as converters go, this is one of the most efficient you can get for the best ET. It’s not the best for street driving but I do it anyway. I don’t have any problems with this converter on the street but all the internet experts will say differently. Selling with or without cast aluminum deep pan. If you have followed my build thread, you’ll know that I don’t use cheap junk on my car. These parts I removed from it are no different. Trans leaks no oil either.

Trans $500
Converter $500 ($900 new)
TCI pan $100
Or
$1000 for all 3

I also will have the Hughes SFI flex plate, B&M ratchet shifter, and driveshaft available that went with all this.
