"Stock long block and stock turbo, e85, 2800 Stock re-stall"
So assuming max 22 PSI, my opinion is; Stock stall D5, locked @ wot, with a GOOD transmission.
FWIW; I have a local buddy who has a NLU trans, stock long block with valve springs (intake has never been off) TE44, 93/alky, 27-30 PSI for about 10 years. He tried a few converters and all slipped way too much for the operating RPM. He just got a 9.5 PTC spec'd by/from Bison. Should be good to go.
