mystery 904 stall converter

well i have this 904 9" stall converter it came with a race built 904 trans i got. the guy didnt know how much stall it was... here is the story i got when i picked up the trans. this came from 11 sec. barracuda that had a 318 in it i know sounds a little far fetched but i did see the engine also. it was a 318 with forged piston .030 over. had a solid roller cam in it. and massively ported x-heads on it.... im assuming this was an all high RPM build so i would assume this converter is prob a 4000 or higher. look at the pics and here are some of the stampings on it.

im guessing the Motts name stamped on it is either the brand/builder or the persons name it was custom built for.
numbers are
11708-904
T-6
P093S
11102996

any info or opinions would be great!!

only issues i have seen with it is the hub had some flash rust on it that i took scotch-brite and removed then greased. and the paint is flaking off the wheel side of it. I was told it worked great but i never rode in the car. the guy was removing the race parts to restore the barracuda.

if you would like to own this converter make me an offer i know this isnt the classifieds i would list it there but i dont like to sell things i dont know anything about but if you want to take a chance on it make me an offer. probably too much converter for anything i will ever build.
i would also trade for a 2800 stall for a 727

thanks for any help!!
