[updated:LAST EDITED ON 30-Dec-02 AT 07:02 PM (EST)]I've just recently rebuilt my 351M, the main crank journals, clearances are .002, connecting rod journals .0175, new cam and cam bearings, lifters. New high volume oil pump. Any thoughts as to why I can't maintain my oil pressure when the engine is hot? I don't think the problem is in the bottom end, thanks for any suggestions.
