727 Lock up converter choices?

townsend said
This information comes from the Dodge truck dealership catalogs. 4058384 transmission with date code 8720 translates to build date June 12 1985. Torque converter part number was 4293065. These numbers were used from 1981 thru 1985. There were no v-8 lock-up high stall converters listed,only low stall. Here is the 1985 description for the 4058384: A727,with long extension, D1 and D2 conventional truck, with 225 engine, with lock-up converter with high stall.

Thanks much. That does help a bunch.
And it fits with this trans being there original one from the truck it's in, build date on door jamb says truck was a 6/85 build.
Same month and year I graduated from high school.
So it can't be old yet.
And I simply wanted some info before I started making calls. I will call milt as suggested above, soon as I can. He's on the east coast, different time zone from me. By the time I get home from work it's after 5 "their time" out there.
I do have a trans parts warehouse that I've bought from in years past, that I'll be calling as soon as I get to take off a lil early so I can make it up there before closing, they're 2 hours away from work with good traffic.
There are no stickers on the front face of the converter. I've seen those before. So then as they go I should have the higher stall version in there now.
And yeah I did see a few rounded over teeth on the ring gear so yeah I will be replacing it with the engine swap.
