Here is the owners homemade engine/run stand. Take note of the pre-oiler that will be used with this engine. This is an original 340 with lots of performance upgrades and thanks to the pre-oiler, this engine has never seen anything less than 60lbs of pressure. This is not an accumulator, it is a separate oil pressure pump that is turned on BEFORE the engine is rotated. This guarantee's plenty of oil fed to the bearings, cam etc.
