My friend (and also a member here) had Brewers rebuild his 833OD that’s going behind a 340 in his 65 Valiant. He dropped it off at one show and picked it up at a later show to save on shipping. IIRC he said the rebuild was right at $700 and did require some new internals. I’d check with him for better info but he’s currently in Afghanistan and communications isn’t the greatest!
