130-150 sounds low for a 3400. If it isn't boiling in the block from air pockets, it is probably a bad head gasket on that engine as well. Was it out of a van by chance? Those tend to blow the rear head gaskets more commonly than the cars do. You have already replaced everything else that it could be from what I see.
Get a coolant pressure tester and see if the cooling system holds.
