What converter is this?

[ScottHeidinger]

I bought a CK full billet 2004R transmission and this converter off craigslist. The guy selling it said it was going to go in a 383 with NOS but it never happened. The trans is still wrapped in plastic with shipping tag from CK and the invoice says 10.5 NS lockup. It's in a Precision box and looks like the original box. I'm trying to figure out what this is and if I should use it or sell it. It's stamped 27spl ls A1014275. Anyone know what it is other than obviously a 10.5 lockup?

bump, would like to know the stall on this particular model as well

I have a high stall version of this same converter that is stamped HS 27spl HS A1014729 and is 3200 rpm stall.
