TH400 with the Novak adapter to mate it to the dana 300. Was rebuilt a year or so ago with the good stuff. Has the correct output spline for the dana 300 case and the Novak adapter. I do not have a case. No converter. Had a high stall and held up to a 700hp BBC for a couple bogs till the T-case blew apart. Good trans. Adapter kit alone is $500. Looking for $650 obo. Will look at trades. Looking for Chevy dana 60 front parts or complete. I got other things to throw in to make up the difference if need be.
